Hardware cursor Coral supports two hardware cursor functions. Each of these hardware cursors is specified as a 64 x 64-pixel area. Each pixel of these hardware cursors is 8 bits and uses the same look-up table as indirect color mode. Double buffer method Double buffer method in which drawing window and display window is switched in units of 1 frame enables the smooth animation. Flipping (switching of display window area) is performed in synchronization with the vertical blanking period using program. Scroll method Independent setting of drawing and display windows and their starting position enables the smooth scrolling. Display colors * Supports indirect color mode which uses the look-up table (color palette) in 8 bits/pixels. * Entry for look-up table (color palette) corresponds to color code for 8 bits, in other words, 256. data is each 6 bits of RGB. Consequently, 256 colors can be displayed out of 260,000 colors. * Supports direct color mode which specifies RGB with 16 bits/pixels. Color

1.4.5 Geometry processing
Coral has a geometry engine for performing the numerical operations required for graphics processing. The geometry engine uses the floating-point format for highly precise operations. It selects the required geometry processing according to the set drawing mode and primitive type and executes processing to the final drawing. Primitives Point, line, line strip, independent triangle, triangle strip, triangle fan, and arbitrary polygon are supported. MVP Transformation MVP Transformation Setting a 4 x 4 transformation matrix enables transformation of a 3D model view projection. Two-dimensional affine transformation is also possible. Clipping Clipping stops drawing of figures outside the window (field of view). Polygons (including concave shapes) can also be clipped. Culling Triangles on the back are not drawn. 3D-2D Transformation This functions transforms 3D coordinates (normalization) into 2D coordinates in orthogonal or perspective projections. View port transformation This function transforms normalized 2D coordinates into drawing (device) coordinates. Primitive setup This function automatically performs a variety of slope computations, etc., based on transforming vertex data into coordinates and prepares for rendering (setup). Log output of device coordinates The view port conversion results are output to the local memory.

1.4.6 2D Drawing
2D Primitives Coral can perform 2D drawing for graphics memory (drawing plane) in direct color mode or indirect color mode. Bold lines with width and broken lines can be drawn. With anti-aliasing smooth diagonal lines also can be drawn. A triangle can be tiled in a single color or 2D pattern (tiling), or mapped with a texture p attern by specifying coordinates of the 2D pattern at each vertex (texture mapping). At texture mapping, drawing/non-drawing can be set in pixel units. Moreover, transparent processing can be performed using alpha blending. When drawing in single color or tiling without Gouraud shading or texture mapping, high-speed 2DLine and high-speed 2DTriangle can be used. Only vertex coordinates are set for these primitives. High-speed 2DTriangle is also used to draw polygons. 2D Primitives
Primitive type Point Line Bold line strip (provisional name) Triangle High-speed 2DLine Arbitrary polygon Description Plots point Draws line Draws continuous bold line This primitive is used when interpolating the bold line joint. Draws triangle Draws lines Compared to line, this reduces the host CPU processing load. Draws arbitrary closed polygon containing concave shapes consisting of vertices
Arbitrary polygon drawing Using this function, arbitrary closed polygon containing concave shapes consisting of vertices can be drawn. (There is no restriction on the count of vertices, however, the polygon with its sides crossed are not supported.) In this case, as a work area for drawing, polygon drawing flag buffer is used on the graphics memory. In drawing polygon, draw triangle for polygon drawing flag buffer using high-speed 2DTriangle. Decide any vertex as a starting point to draw triangle along the periphery. It enables you to draw final polygon form in single color or with tiling/texture mapping in a drawing frame.

1.4.8 Special effects
Anti-aliasing Anti-aliasing manipulates line borders of polygons in sub-pixel units and blend the pre-drawing pixel color with color to make the jaggies be seen smooth. It is used as a functional option for 2D drawing (in direct color mode only). Bold line and broken line drawing This function draws lines of a specific width and a broken line. Line Drawing Attributes
Attribute Line width Broken line Description Selectable from 1 to 32 pixels Set by 32 bit or 24 bit of broken line pattern
* Supports the verticality of starting and ending points. * Supports the verticality of broken line pattern. * Interpolation of bold line joint supports the following modes: (1) Broken line pattern reference address fix mode The same broken line pattern is kept referencing for the period of some pixels starting from the joint and the starting point for the next line. (2) No interpolation * Supports the equalization of the width of bold lines. * Supports the bold line edging. * Not support the Anti-aliasing of dashed line patterns. * For a part overlaid due to connection of bold lines, natural overlay can be represented by providing depth information. (Z value). Shading Supports the shading primitive. Drawing is performed to the body primitive coordinates (X, Y) with an offset as a shade. At this drawing, the Z buffer is used in order to differentiate between the body and shade.

Alpha blending Alpha blending blends two image colors to provide a transparent effect. CORAL supports two types of blending; blending two different colors at drawing, and blending overlay planes at display. Transparent color is not used for these blending options. There are two ways of specifying alpha blending for drawing: (1) Set a transparent coefficient to the register; the transparent coefficient is applied for transparency processing of one plane. (2) Set a transparent coefficient for each vertex of the plane; as with Gouraud shading, the transparent coefficient is linear-interpolated to perform transparent processing in pixel units. In addition to the above, the following settings can be performed at texture mapping. When the most significant bit of each texture cell is 1, drawing or transparency can be set. When the most significant bit of each texture cell is 0, non-drawing can be set. Alpha Blending
Type Drawing Description Transparent ratio set in particular register While one primitive (polygon, pattern, etc.), being drawn, registered transparent ratio applied A transparent coefficient set for each vertex. A linear-interpolated transparent coefficient applied. This is possible only in direct color mode. Overlay display Blends top layer pixel color with lower layer pixel color Transparent coefficient set in particular register Registered transparent coefficient applied during one frame scan
Gouraud Shading Gouraud shading can be used in the direct color mode to provide 3D object real shading and color gradation.
Gray Scale Gouraud Shading Gray scale gouraud shading can be used in the in-direct color(8bit/pixel) mode to draw a blend coefficient layer.

Texture mapping Coral supports texture mapping to map a image pattern onto the surface of plane. The texture n pattern can be laid out in the graphics memory. In this case, max. 4096 x 4096 pixels can be used. For drawing 8-bit color, only point sampling can be specified for texture interpolation; only de-curl can be specified for the blend mode.

1.4.9 Others
Drawing color 8-bit indirect color and 16-bit direct color are supported as a drawing input data. Top-left rule non-applicable mode In addition to the top-left rule applicable mode in which the triangle borders are compatible with CREMSON, the top-left rule non-applicable mode can be used. (In case of non-top-left polygon drawing, an object has to be in a geometry clipping area.) Caution: Use perspective correct mode when use texture at the top-left rule non-applicable mode. Top-left rule non-applicable primitives cannot use Geometry clip function. Non-top-left-part's pixel quality is less than body. (using approximate calculation)

4.1.2 Ready signal mode
The MODE2 pin can be used to set the ready signal level when the bus cycle of the host CPU terminates. For the normally not ready mode, set the software wait to 0 or 1 cycles. When using this device in the normally ready mode, set the software wait to 2 cycles. When using this device in the normally not ready mode, set the software wait to one cycle. (When BS_MODE = H three cycles are needed for the , software wait.) The `normally not ready mode' is the mode in which the CORAL XRDY signal is always in the wait state and Ready is returned only when read/write is ready. The `normal ready mode' is the mode in which the CORAL XRDY signal is always in the Ready state and it is put into the wait state only when read/write cannot be performed immediately.

4.2
Access Mode
4.2.1 SRAM interface
Data can be transferred to/from CORAL using SRAM access protocol. CORAL internal registers and graphics memory are all mapped to the physical address area of the host processor. CORAL uses hardware wait based on the XRDY signal, enabling the hardware wait setting of the host CPU. When using the normally not ready mode, set the software wait to "1". When using the normally ready mode, set the software wait to "2". (When using the BS_MODE signal as "High" level, with the normally ready mode established, set the CPU software wait to three cycles.) Switch the ready mode using the RDY_ MODE signal. CPU Read The host processor reads data from internal registers and memory of CORAL in double-word (32 bit) units. Valid data is output continuously while XRD and XCS are being asserted at a "Low" level after XRDY has been asserted. CPU Write The host CPU writes data to internal registers and memory of CORAL in byte, word(16 bit) and double-word( 32 bit) units.
4.2.2 FIFO interface (fixed transfer destination address)
This interface transfers display lists stored in host memory. Display list information is transferred efficiently using a single address mode DMA transfer. Data can be transferred to FIFO in relation to FIFO buffer area mapped in memory area using SRAM interface or dual address mode.

4.3
DMA Transfer
4.3.1 Data transfer unit
DMA transfer is performed in double-word (32 bits) units or 8 double-word (32 bytes) units. Byte and word access is not supported. Note: 8 double-word transfer is supported only in the SH4 mode.
4.3.2 Address mode
Dual address mode (mode using ACK) DMA is performed at memory-to-memory transfer between host memory and registers mapped in memory space or graphics memory (destination). Both the host memory address and CORAL is used. In the SH4 mode, the 1 double-word transfer (32 bits) and 8 double-word transfer (32 bytes) can be used. When the CPU transfer destination address is fixed, data can also be transferred to the FIFO interface. However, in this case, even the SH4 mode supports only the 1 double-word transfer. DREQ and DRACK pins and SRAM interface signals are used. In V832, the DREQ, DMAAK, and XTC pins and SRAM interface signals are used. Note: The SH3 mode supports the direct address mode; it does not support the indirect address mode. Dual address mode (mode not using ACK) When not using the ACK signal with the dual address mode established, set bit3 at HostBase+0004h (DNA: Dual address No Ack mode) to 1. When the ACK is not used, the DREQ signal is in the edge mode and the DREQ signal is negated per transfer and then reasserted it in the next cycle. If processing cannot be performed immediately inside CORAL, the DREQ signal remains negated. The transfer count register (DTC) of CORAL is not used, so in order to end DMA transfer, write "1" to the DMA transfer stop register (DTS) from the CPU. Note 1: In the dual DMA mode (mode without ACK), the destination address can be used only for the FIFO. In DMA transfer to the graphics memory, etc., use the dual DMA mode. Note 2: DMA read is not supported. Single address mode (FIFO interface) Data is transferred between host memory (source) and FIFO (destination). Only the address output from the host memory is used, and the data is transferred to the FIFO. This mode does not support data write to the host memory. When the FIFO is full, the DMA transfer is suspended. The 1 double-word transfer (32 bits) and the 8 double-word transfer (32 B) can be used. DREQ, DTACK, and DRACK signal are used. Note: The single-address mode is supported only in the SH4 mode.

4.3.3 Bus mode
Coral supports the DMA transfer cycle steal mode and burst mode according to setting of external DMA mode. Cycle steal mode (In the V832 mode, the burst mode is called the single transfer mode.) In the cycle steal mode, the right to use the bus is obtained or released at every data transfer of 1 unit. The DMA transfer unit can be selected from between the 1 double-word (32 bits) and 8 double-words (32 B). Burst mode (In the V832 mode, the burst mode is called the demand transfer mode.) When DMA transfer is started, the right to use the bus is acquired and the transfer begins. The data transfer unit can be selected from between the 1 double-word (32 bits) and 8 double-words (32 B). Note: When performing DMA transfer in the dual-address mode, a function for automatically negating DREQ is provided based on the setting of the DBM register.
4.3.4 DMA transfer request
Single-address mode DMA is started when the CORAL issues an external request to DMAC of the host processor. Set the transfer count in the transfer count register of the CORAL and then issue DREQ. Fix the CPU destination address to the FIFO address. Dual-address mode DMA is started by two procedures: CORAL issues an external request to DMAC of the host processor, or the CPU itself is started (auto request mode, etc.). n Ack use mode, set the transfer count in the I transfer count register of CORAL and then issue DREQ.
Note: In the Ack unused mode and the V832 mode requires no setting of the transfer count register.
4.3.5 Ending DMA transfer
* SH3/SH4 When the CORAL transfer count register is set to 0, DMA transfer ends and DREQ is negated. * V832 When the XTC signal from the CPU is low-asserted while the DMAAK signal to S CORAL is high-asserted, the end of DMA transfer is recognized and DREQ is negated. * The end of DMA transfer is detected in two ways: the DMA status register (DST) is polled, and an interrupt to end the drawing command (FD000000H ) is added to the display list and the interrupt is detected. * In the dual address mode (mode not using ACK), the DMA transfer count register (DTC) is not used, so the DMA ending cannot be determined. The DREQ signal can be negated to end DMA by writing 1 from the CPU to the DMA transfer stop register (DTS) of CORAL at DMA transfer end.

Transfer of Local Display List
This is the mode in which the CORAL internal bus is used to transfer the display list stored in the graphics memory to the FIFO interface. During transfer of the local display list, the host bus can be used for CPU read/write. How to transfer list: Store the display list in the local memory of CORAL, set the transfer source local address (LSA) and the transfer count (LCO), and then issue a request (LREQ). Whether or not the local display list is currently being transferred is checked using the local transfer status register (LSTA).

5 Graphics Memory
5.1 Configuration
The Coral uses local external memory (Graphics memory) for drawing and display management. The configuration of this Graphics memory is described as follows:
5.1.1 Data type
The Coral handles the following types of data. Display list can be stored in the host (main) memory as well. Texture/tile pattern and text pattern can be defined by a display list as well. Drawing Frame This is a rectangular image data field for 2D/3D drawing. The Coral is able to have plural drawing frames and display a part of these area if it is set to be bigger than display size. The maximum size is 4096x4096 pixel in 32 pixel units. And both indirect color ( 8 bits / pixel) and direct color ( 16 bits / pixel) mode are applicable. Display Frame This is a rectangle picture area for display. The Coral is able to set display layer up to 6 layers. Z Buffer Z buffer is required for eliminating hidden surfaces. In 16 bits modes, 2 bytes and in 8 bits mode, 1 byte are required per 1 pixel. This area has to be cleared before drawing. Polygon Drawing Flag Buffer This area is used for polygon drawing. It is required 1 bit memory area per 1 pixel and 1 x-axis line area both backward and forward of it. This area has to be cleared before drawing.

Frame Management
5.2.1 Single Buffer
The entire or partial area of the drawing frame is assigned as a display frame. The display field is scrolled by relocating the position of the display frame. When the display frame crosses the border of the drawing frame, the other side of the drawing frame is displayed, assuming that the drawing frame is rolled over (top and left edges assumed logically connected to bottom and right edges, respectively). To avoid the affect of drawing on display, the drawing data can be transferred to the Graphics Memory in the blanking time period.
5.2.2 Double Buffer
Two drawing frames are set. While one frame is d isplayed, drawing is done at the other frame. Flicker-less animation can be performed by flipping these two frames back and forth. Flipping is done in the blanking time period. There are two flipping modes: automatically at every scan frame period, and by user control. The double buffer is assigned independently for the L2, L3, L4, L5 layers.
5.3
Memory Access
5.3.1 Memory Access by host CPU
Graphics memory is mapped linearly to host CPU address field. The host CPU can access the Graphics memory like a SRAM.
5.3.2 Priority of memory accessing
The priority of Graphics memory accessing is the follows: 1. 2. 3. 4. 5. Refresh Video Capture Display processing Host CPU accessing Drawing accessing

The fundamental flow is: Palette Layer selection Blending. The palettes convert 8 -bit color codes to the RGB format. The layer selector exchanges the layer overlay sequence arbitrarily. The blender performs blending using the blend coefficient defined for each layer or overlays in accordance with the transparent-color definition. The L0 layer corresponds to the C layer for previous products and shares the palettes with the cursor. As a result, the L0 layer and cursor are overlaid before blend operation. The L1 layer corresponds to the W layer for previous products. To implement backward compatibility with previous products, the L1 layer and lower layers are overlaid before blend operation. The L2 to L5 layers have two paths; in one path, these layers are input to the blender separately and in the other, these layers and the L1 layer are overlaid and then are input to the blender. When performing processing using the extended mode, select the former; when performing the same processing as previous products, select the latter. It is possible to specify which one to select for each layer.

(2) Overlay mode Image layer overlay is performed in two modes: simple priority mode, and blend mode. In the simple priority mode, processing is performed according to the transparent color defined for each layer. When the color is a transparent color, the value of the lower layer is used as the image value for the next stage; when the color is not a transparent color, the value of the layer is used as the image value for the next stage. Dview = Dnew (when Dnew does not match transparent color) = Dlower (when Dnew matches transparent color) When the L1 layer is in the YCbCr mode, transparent color checking is not performed for the L1 layer; processing is always performed assuming that transparent color is not used.
In the blend mode, the blend ratio "r" defined for each layer is specified using 8-bit tolerance, and the following operation is performed: Dv iew = Dnew*r + Dlower*(1 - r) Blending is enabled for each layer by mode setting and a specific bit of the pixel is set to "1". For 8 bits/pixel, the MSB of RAM data enables blending; for 16 bits/pixel, the MSB of data of the relevant layer enables blending; for 24 bits/pixel, the MSB of the word enables blending.
(3) Blend coefficient layer In the normal blend mode, the blend coefficient is fixed for each layer. However, in the blend coefficient layer mode, the L5 layer can be used as the blend coefficient layer. In this mode, the blend coefficient can be specified for each pixel, providing gradation, for example. When using this mode, set the L5 layer(L5M and L5EM register) to 8 bits/pixel, window display mode and extend overlay mode.

Coral scans the logical graphics space as if the entire space is rolled over in both the horizontal and vertical directions. Using this function, if the display frame crosses the border of the logical graphics space, the part outside the border is covered with the other side of the logical graphics space, which is assumed to be connected cyclically as shown below:

The expression of the X and Y coordinates in the frame and their corresponding linear addresses (in bytes) is shown below. A(x,y) = x x bpp/8 + 64wy (bpp = 8 or 16)
The origin of the displayed coordinates has to be within the frame. To be more specific, the parameters are subject to the following constraints: 0 DX < w x 64 x 8/bpp (bpp = 8 or 16) 0 DY < H
DX, DY, and DA have to indicate the same point within the frame. In short, the following relationship must be satisfied. DA = OA + DX x bpp/8 + 64w x DY (bpp = 8 or 16)

Color data is displayed in the following modes:
Indirect color (8 bits/pixel) In this mode, the index of the palette RAM is displayed. Data is converted to image data consisting of 6 bits for R, G, and B via the palette RAM and is then displayed. Direct color (16 bits/pixel) Each level of R, G, and B is represented using 5 bits. Direct color (24 bits/pixel) Each level of R, G, and B is represented using 8 bits. YCbCr color (16 bits/pixel) In this mode, image data is displayed with YCbCr = 4:2:2. Data is converted to image data consisting of 8 bits for R, G, and B using the operation circuit and is then displayed.
The display colors for each layer are shown below.

"Pn" stands for the corresponding palette RAM.
Four palettes are used as follows:
Palette 0 (P0) This palette corresponds to the C-layer palette for previous products. This palette is used for the L0 layer. This palette can also be used for the cursor. Palette 1 (P1) This palette corresponds to the M/B layer palette for previous products. In the compatibility mode, this palette is common to layers L1 to 5. In the extended mode, this palette is dedicated to the L1 layer. Palette 2 (P2) This palette is dedicated to the L2 layer. This palette can be used only for the extended mode. Palette 3 (P3) This palette is dedicated to the L2 layer. This palette can be used only for the extended mode.

Cursor
6.4.1 Cursor display function
CORAL can display two hardware cursors. Each cursor is specified as 64 x 64 pixels, and the cursor pattern is set in the Graphics Memory. The indirect color mode (8 bits/pixel) is used and the L0 layer palette is used. However, transparent color control (handling of transparent color code and code 0) is independent of L0 layer. Blending with lower layer is not performed.
6.4.2 Cursor control
The display priority for hardware cursors is programmable. The cursor can be displayed either on upper or lower the L0 layer using this feature. A separate setting can be made for each hardware cursor. If part of a hardware cursor crosses the display frame border, the part outside the border is not shown. Usually, cursor 0 is preferred to cursor 1. However, with cursor 1 displayed upper the L0 layer and cursor 0 displayed lower the L0 layer, the cursor 1 display is preferred to the cursor 0.

Display Scan Control
6.5.1 Applicable display
The following table shows typical display resolutions and their synchronous signal frequencies. The pixel clock frequency is determined by setting the division r te of the display reference clock. The display a reference clock is either the internal PLL (400.9 MHz at input frequency of 14.318 MHz), or the clock supplied to the DCLKI input pin. The following table gives the clock division rate used when the internal PLL is the display reference clock: Table 4-1

6.5.2 Interlace display
CORAL can perform both a non-interlace display and an interlace display. When the DCM register synchronization mode is set to interlace video (11), images in memory are output in odd and even rasters alternately to each field, and one frame (odd + even fields) forms one screen. When the DCM register synchronization mode is set to interlace (10), images in memory are output in raster order. The same image data is output to odd fields and even fields. Consequently, the count of rasters on the screen is half of that of interlace video. However, unlike the non-interlace mode, there is a distinction between odd and even fields depending on the phase relationship between the horizontal and vertical synchronous signals.

The external synchronous signal
The display scan can be performed by synchronizing horizontal/vertical synchronous signal from the external. In selecting the external synchronization mode, Coral is sampling the HSYNC signal and displays the synchronizing the external video signal. Either the internal PLL clock or the DCL KI input signal could be selected for the sampling clock. Also, the superimposed analog output is performed by the chroma key process. The following diagram shows an example of the external synchronization circuit.

An example of the external synchronization circuit The external synchronization mode is performed by setting the ESY bit of the DCM register. In setting the external synchronization mode, HSYNC, VSYNC, and EO pin of Coral is changed to the input mode. After that it needs to be provided the synchronous signal by using the 3 state buffer from the external. When turning off the external synchronization mode, Coral internal ESY bit needs to be switched OFF after disconnecting the synchronous input signal from the external. The buffer of the external synchronization signal must not be switched ON when the synchronous output signal of Coral is ON. Follow the previous instruction to prevent simultaneous ON from occurring. In using the external synchronous signal with the display clock based on the internal PLL, Coral extends the clock period and fits the clock phase with the horizontal synchronous signal phase after inputting the horizontal synchronous pulse. The following caution is necessary. In case of connecting the high speed transmit signal, such as LVDS, with the digital RGB output, PLL with a built-in the high speed serial transmission is temporally unstable due to this connection. Therefore,

The finite state diagram is controlled by the horizontal resolution counter. The period of outputting the signal is assigned the Disp state. When the value of the horizontal resolution counter matches that of the HDP register, it ends to output the signal and the current state is transmitted from Disp state to Fporch state (front porch). In the Fporch state, when the value of the vertical resolution register matches that of the HSP register, the current state is transmitted to the Sync state. In this state, it waits for the horizontal synchronous signal from the external. Coral detects the negative edge of the horizontal synchronous pulse from the external and synchronizes it. In detecting the horizontal synchronous signal from the external, the current state is transmitted to the Bporch state (back porch). The horizontal resolution register does not count in the Sync state, instead the horizontal synchronous counter is incremented from zero. When the value of this counter matches the setting value of the HSW register, the current state is transmitted to the Bporch state without detecting the horizontal synchronous signal form the external. When the value of the horizontal resolution counter matches that of the HTP register in the Bporch state, the horizontal resolution counter is reset, and also the current state is transmitted to the Disp state and it begins to display the next cluster.

7 Video Capture
7.1 Format
7.1.1 Input Data Format
Input a digital video stream in the ITU RBT-656 format. NTSC and PAL signals are both supported.
7.1.2 Video Signal Capture
When the VIE bit of the video capture mode register (VCM) is 1, Coral is enabled to capture video stream data from the 8-bit VI pin in synchronization with the CCLK clock. Only a digital video stream conforming to ITU -RBT656 can be processed. For this reason, a Y,Cb,Cr 4:2:2 format to which timing reference codes are added is used. The video stream is captured according to the timing reference codes; Coral automatically supports both NTSC and PAL. However, to detect error codes, set NTSC/PAL in the VS bit of VCM. If NTSC is not set, reference the number of data in the capture data count register (CDCN). If PAL is not set, reference the number of data in the capture data counter register (CDCP). If the reference data does not match the stream data, bit 4 to bit 0 of the video capture status register (VCS) will be values other than 0000.
7.1.3 Non-interlace Transformation
Captured video graphics can be displayed in non-interlaced format. Two modes (BOB and WEAVE) can be selected at non-interlace transformation.
- BOB Mode In odd fields, the even-field rasters generated by average interpolation are added to produce one frame. In even fields, the odd-field rasters generated by average interpolation are added to produce one frame. The BOB mode is selected by enabling vertical interpolation with the VI bit of the video capture mode register (VCM) and setting the L1IM bit of the L1-layer mode register (L1M) to 0.
- WEAVE Mode Odd and even fields are merged in the video capture buffer to produce one frame. Vertical resolutions in the WEAVE mode are higher than those in the BOB mode but raster dislocation appears at moving places. The WEAVE mode is selected by disabling vertical interpolation with the VI bit of VCM and setting the L1IM bit of L1-layer mode register(L1M) to 1.

7.2.2 Synchronous Control
Video graphics data is written to scan-independent memory for display. Memory for video capture is controlled by the ring buffer method. When graphics data for one frame is ready in memory, the frame is displayed. If the video capture frame rate is different from the display frame rate, a frame is omitted or the same frame is displayed continuously.
7.2.3 Area Allocation
Allocate an area of about 2.2 frames to the video capture buffer. The size of this area is equivalent to the size that considers the margin equivalent to the double buffer of the frame. Set the starting address and upper-limit address of the area in the CBOA/CBLA registers. Here, specify the raster start position as the upper-limit address. To allocate n rasters as the video capture buffer, set the upper-limit value as follows: CBLA = CBOA + 64n X CBS If CBLA does not match the head of a raster, video capture data is written beyond the upper limit by only 1 raster (max.). Note that if other meaningful data is held in the area, the user-intended operation is hindered by overwriting. For reduced display, allocate the buffer area of the reduced frame size.

To capture and display video graphics, set the L1 layer to the capture synchronous mode (L1CS = 1). In the capture synchronous mode, the L1 layer displays the latest frame in the video capture buffer. The display addresses used in the normal mode are ignored. The stride of the L1 layer must match that of the video capture buffer. displayed graphics have oblique distortion. If they do not match, the
Match the display size of the L1 layer with the reducted graphics size of the video capture. Setting the display size of the L1 layer larger than the capture image size causes display of invalid data. The L1 layer supports selection of the RGB display format and YcbCr display format. To capture video graphics, select the YcbCr display format (WYC = 1).
7.2.5 Interlace Display
The graphics captured in the video capture buffer in the WEAVE mode can be displayed in interlace. Interlace display setting is the same as WEAVE mode setting. Select `Interlace & video display' for display scan. Flicker appears in moving video graphics. To prevent flicker, set the OO (Odd Only) bit of the capture buffer mode register (CBM) to "1".

7.3
Scaling
7.3.1 Video Reduction Function
When the CM bits of the video capture mode register (VCM) are 11, Coral reduces the video screen size. The reduction can be set independently in the vertical and horizontal scales. The reduction is set per line in the vertical direction and in 2-pixel units in the horizontal direction. The scale setting value is defined by an input/output value. It is a 16-bit fixed fraction where the integer is represented by 5 bits and the fraction is represented by 11 bits. Valid setting values are from 0800H to FFFFH. Set the vertical direction at bit 31 to bit 16 of the capture scale register (CSC) and the horizontal direction at bits 15 to bit 00. The initial value for this register is 08000800H (once). An example of the expressions for setting a reduction in the vertical and horizontal directions is shown below. 576 490 lines 1.176x2048=2408 Reduction in horizontal direction 720 648 pixels 1.111x2048=2275 Therefore, 096808E3H is set in CSC. The capture horizontal pixel register (CHP) and capture vertical pixel register (CVP) are used to limit the number of pixels processed during scaling. They are not used to set scaling values. Clamp processing is performed on the video streaming data outside the values set in CHP and CVP. Usually, the defaults for these registers are used.
Reduction in vertical direction
576/490 = 1.176 0968H 720/648 = 1.111 08E3H
7.3.2 Vertical Interpolation
When the VI bit of the video capture mode register (VCM) is "0", data in the same field is used to interpolate the interlace screen vertically. The interlace screen is doubled in the vertical direction. When the VI bit is "1", the interlace screen is not interpolated vertically.

Error Handling
7.4.1 Error Detection Function
If an expected control code is not detected in the input video stream, an error occurs. If an error occurs, the status is returned to the register.

The "OC CC Matrix" is a "4 x 4" matrix consisting of a ModelView matrix and a Projection matrix. If "Zoc" is not contained in the input parameter of the G_Vertex packet (Z-bit of GMDR0 is off), (OC CC) coordinate transformation is processed as "Zoc = 0". When GMDR0[0] is 0 (orthogonal projection transformation), OC CC coordinate transformation is processed as "Wcc = 1.0".

W clipping is
Clipping-on/-off View volume clipping-on/-off can be switched by using the clip boundary values set by the G_ViewVolumeXYClip/Zclip/WClip packet. To switch view volume clipping to off, set the maximum and minimum values of the geometry data format (IEEE single-precision floating point(*1)) in the "Clip.max" value(*2) and "Clip.min" value(*3), respectively. In this case, `All coordinate transformation results' can be evaluated as within view volume range, making it possible to obtain the effect of view volume clipping-off. This method is valid only when W clipping does not occur. When a clip boundary value (Wmin) that causes W clipping to occur is set, clipping is also performed for each clip area. Consequently, set an appropriate clip boundary value for Clip. Max value. and Clip. Min value., respectively. If other values are set in "Clip.max" and Clip.min, view volume clipping-on operates. The coordinate transformation result is always compared with the values set in "Clip.max" and "Clip.min". *1: Maximum value = 0x7f7fffff, minimum value = 0xff7fffff *2: Xmin,Ymin, Zmin, Wmin *3: Xmax, Ymax, Zmax

"W" clipping at orthogonal projection transformation "W" at orthogonal projection transformation (GMDR0[0] = 0) is treated as "Wcc=1.0". For this reason, to suppress "W" clipping, the set "Wmin" value must be larger than 0 and 1.0 or less. Relationship with drawing clip frame For the following reasons, the clip boundary values of the view volume should be set so that the values after DC coordinate transformation will be larger than the drawing clip frame (2 pixels or more). (1) "XY" on the view volume clip frame of the "CC" coordinate system may be drawn one pixel outside or inside the frame due to an operation error when it is finally mapped to the "DC" coordinate system. (2) When the end point of a line overlaps the view volume frame mapped to the "DC" coordinate system, there are two cases, where the dots on the frame are drawn, and not drawn depending on the specifying of the line drawing attribute (end point drawing/non-drawing). (3) When the start point of a line overlaps the view volume frame mapped to the "DC" coordinate system, the dots on the frame are always drawn. When the line drawing attribute is `end point non-drawing,' the dots on the frame are drawn at the starting point, but they may not be drawn at the end point. (4) When applying to triangle and polygon drawing the rasterizing rule `dots containing center of pixel drawn. Dots on right side and base of triangle not drawn.' depending on the value of the fraction, a gap may be produced between the right side and base of the frame.

In CORAL, a triangle direction can be defined and a mode in which drawing for the back face is inhibited (back face carling) is supported. The on/off operation is controlled by the GMDR2[0] setting. GMDR2[0] must be set to 1 only when back face carling is required. When back face carling is not required such as in `line,' `point,' and `polygon primitive,' GMDR2[0] must be set to 0.

After the calculation of coordinates by the geometry engine, CORAL draws data in the drawing frame in the graphics memory that finally uses the drawing coordinates (device coordinates). Drawing frame is treated as 2D coordinates with the origin at the top left as shown in the figure below. The maximum coordinates is 4096 x 4096. Each drawing frame is located in the G raphics Memory by setting the address of the origin and resolution of X direction (size). Although the size of Y direction does not need to be set, Y coordinates which are max. at drawing must not be overlapped with other area. In addition, at drawing, s pecifying the clip frame (top left and bottom right coordinates) can prevent the drawing of images outside the clip frame.

Concerning 1 and 2 above, 2-term logic operation is performed between source and destination data and its result can be stored. Setting a transparent color enables a drawing of a specific pixel with transmission. If part of the source and destination of the BLT field are physically overlapped in the display frame, the start address (from which vertex the BLT field to be transferred) must be set correctly.

CORAL can handle three bit map data formats: indirect color mode (8 bits/pixel), direct color mode (16 bits/pixel), and binary bit map (1 bit/pixel). The binary bit map is used for character/font patterns, where foreground color is used for bitmap = 1 pixel, and background color (background color can be set to be transparent by setting) is applied for bitmap = 0 pixels.

This just simply masks the upper bits of the applied (S, T) coordinates. When the texture pattern size is 64 x 64 pixels, the lower 6 bits of the integer part of (S, T) coordinates are used for S and T coordinates. Cramp When the applied (S, T) coordinates is either negative or larger than the specified texture pattern size, cramp the (S, T) coordinate as follows instead of texture:
S<0 S > Texture X size - 1 S=0 S = Texture X size - 1
Border When the applied (S, T) coordinate is either negative or larger than the specified texture pattern size, the outside of the specified texture pattern is rendered in the `border' color.

9.4.4 Filtering
CORAL supports two texture filtering modes: point filtering, and bi-linear filtering.
Point filtering This mode uses the texture pixel specified by the (S, T) coordinates as they are for drawing. The nearest pixel in the texture pattern is chosen according to the calculated (S, T) coordinates.
0.5 0.0 1.0 1.5 2.0
0.5 1.0 1.5 2.0
Bi-linear filtering The four nearest pixels specified with (S, T) coordinate are blended according to the distance from specified point and used in drawing.
0.5 0.0 C00 0.5 1.0 1.5 2.0 C01 C11 C10 1.0 1.5 2.0
9.4.5 Perspective correction
This function corrects the distortion of the 3D perspective in the texture mapping. For this correction, the `Q' component of the texture coordinates (Q = 1/W) is set based on the W component of 3D coordinates of the vertex. When the texture coordinates are large values, the texture may not be drawn correctly when perspective correction is performed. This phenomenon occurs due to the precision limitation of the arithmetical unit for perspective correction. The coordinates for the texture that cannot be drawn normally vary with the value of the Q component; as a guide, when this value, texture coordinates (S, T) is smaller than -2048 or larger than 2048, normal drawing results are less likely to be obtained.

9.4.6 Texture blending
CORAL supports the following three blend modes for texture mapping: De-curl This mode displays the selected texture pixel color regardless of the polygon color. Modulate This mode multiplies the native polygon color (CP ) and selected texture pixel color (C T) and the result is used for drawing. Rendering color is calculated as follows (CO): C0 = CT x CP Stencil This mode selects the display color from the texture color with MSB as a flag. MSB = 1: Texture color MSB = 0: Polygon color
9.4.7 Bi-linear high-speed mode
Bi-linear filtering is performed at high speed by creating normal texture data in advance with four-pixel redundancy for one pixel. One pixel requires information of about four pixels, so an area of four times the normal area is used. This data format can only be used only for the bi-linear filtering mode; it cannot be used for the point sampling mode. The color mode is limited to 16-bit color.

Rendering
9.5.1 Tiling
Tiling reads the pixel color from the correlated tiling pattern and maps it onto the polygon. The tiling determines the pixel on the pattern read by pixel coordinates to be drawn, irrespective of position and size of primitive. The tiling pattern size is limited to within 64 x 64 pixels. (at 16-bit color)
Example of Tiling
9.5.2 Alpha blending
Alpha blending blends the drawn in frame buffer to-be-drawn pixel or pixel already according to the alpha value set in the alpha register. This function cannot be used simultaneously with logic operation drawing. It can be used only when the direct color mode (16 bits/pixel) is used. The blended color C is calculated as shown below when the color of the pixel to be drawn is CP, the color of frame buffer is CF , and the alpha value is A: C = CP x A + (1-A) x CF The alpha value is specified as 8-bit data. 00h means alpha value 0% and FFh means alpha value 100%. When the texture mapping function is enabled, the following blending modes can be selected:
Normal Blends post texture mapping color with frame buffer color Stencil Uses MSB of texcel color for ON/OFF control: MSB = 1: Texcel color MSB = 0: Frame buffer color Stencil alpha Uses MSB of texcel color for /OFF control: MSB = 1: Alpha blend texcel color and current frame buffer color MSB = 0: Frame buffer color
Note: MSB of frame buffer is drawn MSB of texcel in both stencil and stencil alpha mode. Therefore in case MSB of texcel is MSB=0, a color of frame buffer is frame buffer, but MSB of frame buffer is set to 0.

9.5.4 Hidden plane management
CORAL supports the Z buffer for hidden plane management. This function compares the Z value of a new pixel to be drawn and the existing Z value in the Z buffer. Display/not display is switched according to the Z -compare mode setting. Define the Z -buffer access options in the ZWRITEMASK mode. The Z compare operation type is determined by the Z compare mode. Either 16 or 8 bits can be selected for the Z-value.

9.8.1 Shadowing
The Coral supports a shadow primitive which is same shape as a body. A shadow is drawn in a position shifted for a device coordinate(X, Y) by setting the OverlapXY command. And by setting the OverlapZ, it is possible to control a drawing result to avoid twice rendering in alpha blend or logical calculation. - Line Two shadow lines are drawn in a line shadowing. One is a shadow line and another is a shadow composition line. A shadow composition line is used for avoiding an overlap with body line. And drawing priority can be set for rendering performance or anti-aliasing.
- Triangle and polygon A shadow primitive are drawn in a triangle and polygon shadowing. Drawing priority is fixed as a body primitive is first.

10.1.2 Parameter format
The parameter format of the geometry command depends on the value set in the D field of GMDR0. When the D field is "00", all parameters are handled in the floating-point format. When the D field is "01", colors are handled as the packed RGB format, and others are handled as the fixed-point format. When the D field is "11", XY is handled as the packed integer format, colors are handled as the packed RGB format, and others are handled as the fixed-point format. In the following text, the floating-point format is suffixed by .float, the fixed point format is suffixed by .fixed, and the integer format is suffixed by .int. Set GMDR0 properly to match parameter suffixes. Rendering command parameters conform to the MB86290A data format.

The G_Vertex command sets vertex parameters and processes and draws the geometry of the primitive specified by the G_Begin* command. Note the following when using this command: * Required parameters depend on the setting of the GMDR0 register. Proper values must be set as the mode values of the MDR0 to MDR4 registers to be finally reflected at drawing. That is, when "Z" comparison is made (ZC bit of MDR1 or MDR2 = 1), the Z bit of the GMDR0 register must be set to 1. When Gouraud shading is performed (SM bit of MDR2 = 1), the C bit of the GMDR0 register must be set to 1. When texture mapping is performed (TT bits of MDR2 = 10), the ST bit of the GMDR0 register must be set to 1. * When the Z bit of the GMDR0 register is 0, input "Z" (Zoc) is treated as "0". * Use values normalized to 0 and 1 as texture coordinates (S, T). * When the color RGB is floating-point format, use values normalized to 0 and 1 as the 8-bit color value. For the packed RGB, use the 8-bit color value directly. * The GMDR1 register is valid only for line drawing; it is ignored in primitives other than line. * The GMDR2 register matters only when a triangle (excluding a polygon) is drawn. At primitives other than triangle, set "0". * The use of both G_BeginE(G_BeginEcont) to G_EndE, and G_VertexLOG/NopLOG is not assured. * G_VertexNopLOG, except for the primitive as point is not assured.

DTC is a readable/writable 32-bit register which sets the transfer count in either one long-word (32 bits) or 32 bytes units. When "1h" is set transfer is performed once. However, when "0h" is set, it indicates the maximum transfer count and 16M (16,777,216) data are transferred. During DMA transfer, the remaining transfer count is shown, therefore, the register value cannot be overwritten until DMA transfer is completed. Note: This register need not be set in a mode in which Dual DMA ACK is not used, or the V832 mode.

DBM (DMA Bus request Mode) Selects DREQ mode used in DMA transfer in dual-address mode 0: 1: DREQ is not negated during DMA transfer irrespective of cycle steal or burst mode. DREQ is negated irrespective of cycle steal or burst mode when CORAL cannot receive data (that is, when Ready cannot be returned immediately). When CORAL is ready to receive data, DREQ is reasserted (When DMA transfer is performed in the single-address mode, DREQ is controlled automatically).
Bit 2
DAM (DMA Address Mode) Selects DMA address mode in issuing external request 0: 1: Dual address mode Single address mode (SH4 only)
Bit 3
DNA (Dual address No Ack mode) This bit is selected when using the dual-address-mode DMA that does not use the ACK signal. 0: 1: Uses dual-address-mode DMA that uses ordinary ACK signal Uses dual-address-mode DMA that does not use ACK signal Detection of the DREQ edge is supported; DREQ is negated per transfer. When data cannot be received irrespective of the Bit1 setting, DREQ continues being negated.

When n is set, with Offset = 0, the frequency division rate is 1/(2n + 2). When m is set, with Offset = 100h, the frequency division rate is 1/(m + 1). Basically, these are setting parameters with the same function (2n + 2 = m + 1). Because of this, m = 2 n + 1 is established. When n is set to the SC field with Offset = 0, 2n + 1 is reflected with Offset = 100h. Also, when PLL is selected as the reference clock, frequency division rates 1/1 to 1/5 are non-functional even when set; other frequency division rates are assigned.

DREQ sampling and channel priority determination for SH mode (DREQ = level detection) In the cycle steal mode, even when DREQ is already asserted at the 2nd DREQ sampling, the right to use the bus is returned to the CPU temporarily. In the burst mode, DMAC secures the right to use the bus unless DREQ is negated.
Fig. 10.9 SH4 Single-address DMA Write (Transfer of 1 Long Word)
CORAL writes data according to the DTACK assert timing. When data cannot be received, the DREQ signal is automatically negated. And then the DREQ signal is reasserted as soon as data reception is ready.

Example: DMA operation when DMA transfer performed twice
(1) The CPU accesses the DREQ issue register (DRQ) of Coral to issue DREQ. (2) The right to use bus is transferred from the CPU to the DMAC. (3) In the first DMAC cycle, write is performed to CORAL and DREQ is negated; DREQ is reasserted in the next cycle. (4) The right to use bus is returned to the CPU and the DREQ edge is detected, so the right to use bus is transferred to the DMAC. (5) The second write operation is performed and DREQ is negated, but DREQ is reasserted because CORAL does not recognize that the transfer has ended. (6) The right to use bus is transferred to the CPU, so the CPU writes to the DTS register of CORAL to negate DREQ.

Non-interlace Timing
In the above diagram, VTR, HDP, etc., are the setting values of their associated registers.
The VSYNC/frame interrupt is asserted when display of the last raster ends. When updating display parameters, synchronize with the frame interrupt so no display disturbance occurs. Calculation for the next frame is started immediately after the vertical synchronization pulse is asserted, so the parameters must be updated by the time that calculation is started.

1) Enable the hardware wait for the areas to which CORAL is connected. When the normally not ready mode (RDY_MODE = 0) is used, set the software wait count to "1". When the normally ready mode (RDY_MODE = 1) is used, set the count to "2". When the normally ready mode is used (RDY_MODE = 1) and BS_MODE = L, set the software wait to 2. When the normally ready mode is enabled and BS_MODE = H, set the software wait to "3". 2) When starting DMA by issuing an external request, do so after setting the transfer count register (DTCR) and mode setting register (DSUR) of CORAL to the same value as the CPU setting. In the dual DMA without ACK mode or V832 mode, there is no need to set DTCR. 3) When CORAL is read-/write-accessed from the CPU during DMA transfer, do not access the registers and memories related to DMA transfer. If these registers and memories are accessed, reading and writing of the correct value is not assured. 4) Set DREQ (DMARQ) to "Low" level detection. 5) Set the DACK/DRACK of SH to high active output, DMAAK of V832 to high active, and XTC of V832 to low active.
12.5
SH3 Mode
1) When the XRDY pin is low, it is in the wait state. 2) DMA transfer in the single-address mode is not supported. 3) DMA transfer in the dual-address mode supports the direct address transfer mode, but does not support the indirect address transfer mode. 4) 16-byte DMA transfer in the dual-address mode is not supported. 5) The XINT signal asserts low active signal.
12.6
SH4 Mode
1) When the XRDY pin is low, it is in the ready state. 2) At DMA transfer in the single-address mode, transfer from the main memory (SH memory) to FIFO of CORAL can be performed, but transfer from CORAL to the main memory cannot be performed. 3) DMA transfer in the single-address mode is performed in units of 32 bits or 32 bytes. 4) SH4-mode 32-byte DMA transfer in the dual-address mode supports inter-memory transfer, but does not support transfer from memory to FIFO. 5) The XINT signal asserts low active signal.
