AL260 ?2002,2003-copyright by averlogic technologies, corp. version b1.0 15 8 general function description 8.1 function blocks AL260 provide a fully programmable structure allowing video stream process more flexible. the AL260 data process is executed by parsing in the modules such as capture, down scale, memory, up scale and mixer. in each module, data will be manipulated corresponding to the setting of registers. due to the lack of the number of registers, some registers require banking to other page for access. there are 4 group registers, base control registers, capture control registers, memory control registers and display control registers. the value of base register 0eh determines which group of registers is taken effect. if register 0eh is programmed to value 00, the group of base control registers is chosen; and the register 0eh with value 01 is for capture register group, value 02 is for memory register group and value 03 is for display register group. the register 0eh must be set to corresponding value before that group of register can be accessed. register group id group register description symbol example 00 access only base control registers bas# bas#16 01 access capture and base control registers cap# cap#20 10 access memory and base control registers mem# mem#32 0eh <1:0> 11 access display and base control registers dis# dis#61 8.2 viu (video input unit) AL260 accepts 16/8bit yuv 4:2:2 (ntsc/pal) video data stream with itu-r-656/601 standards. applying averlogic proprietary scaling algorithm, the video stream can be scaled down to accommodate required output resolutions with high quality scaling effect. the high quality scaling engine also ensures full screen output display. 8.2.1 input data format the AL260 is an integrated video processor that automatically detects and converts multiple video formats. the index and base registers provide user an expansion of the
AL260 ?2002,2003-copyright by averlogic technologies, corp. version b1.0 16 control registers, which implements easy control of the input and the desired output format. the base registers control the input type and target format. the AL260 accepts two data formats: 8-bit itu-r bt.656 (ccir656) and 16-bit ccir601 422. the clock and sync signal pins separate for rgb or yuv while the yuv data share the same pins as rgb data. for detailed applications, please refer to AL260 application notes. 8.2.2 video capture and down scale engine the AL260 has a high-quality scaling engine performing proprietary scaling operations independently in both horizontal and vertical direction with 4-line, high precision interpolation.
AL260 ?2002,2003-copyright by averlogic technologies, corp. version b1.0 17 8.2.3 automatic positioning registers the AL260 can detect and report input capture timing for auto-adjustment function. it detects the starting and ending positions of active video in both direction (horizontal and vertical) and ensures the output fit properly into the display region. the data threshold value defines the sensibility of valid data. the capture data will be sampled and qualified base upon the value of data threshold, so that it can determine the starting point and ending point of an active line or an active frame. 8.2.4 pll programming for memory and display clock AL260 embedded 2 independent 200mhz pll-based clock generator. one is used to generate sdram clock, the other is for output clock. they are all reference input clock from xin (generally 14.318mhz). there are 3 operation modes in defined in pll register: power down mode, bypass mode and normal mode. power down mode forces fout to low and pll in low power consumption state (<10uw). bypass mode provides fout with the same frequency as fin. normal mode synthesizes fout by programming suitable divider values. it needs a tready time (pull_in time + locking time) for pll to re-lock the fin clock when pll wakes up from power mode to normal mode. in general, it should be reserved a tread time for re-locking when pll is changed to normal mode from power mode or bypass mode, or when any divider setting is changed. 8.3 miu (memory interface unit) miu supports sdram 32bit bus width interface. AL260 supports various sdram configurations, such as 512kx16, 2ea. it uses sequential burst mode to control sdram memory that operates at minimum 120mhz of clock frequency. for detailed operation of sdram, please reference memory specifications. 8.3.1 dram bandwidth consideration the AL260 uses external drams for the purpose of frame rate conversion between the
AL260 ?2002,2003-copyright by averlogic technologies, corp. version b1.0 18 input video and the output video device. the frame rate conversion for video is done by double buffering. 8.3.2 dram input/output windows the proceeding diagrams will describe the dram input control. the dram input data size depends on the horizontal capture destination size. after the input data size has been defined, the memory address of input data can be determined by the register dram input stride. the dram input stride can be programmed to provide extra memory space for input data. 8.3 vpu (video processing unit) AL260 identifies video input sources including progressive film (24/25 fames/sec) and interlaced video (50/60 fields/sec) and selects appropriate de-interlacing algorithm for video enhancement. vpu supports film detection with inverse 3:2 or 2:2 pull down and averlogic proprietary de-interlacing. when AL260 detects the video source as film, then
AL260 ?2002,2003-copyright by averlogic technologies, corp. version b1.0 19 progressive scan frames will be reassembled and output twice input rate such as 50/60 frame/sec. otherwise, it will be taken as interlaced video source, and processed by using de-interlacing to reduce video artifacts. the scaling engine offers scale-up effect by applying cubic scaling algorithm. it supports independent scale-up in both horizontal and vertical direction with 4-line, high precision interpolation. AL260 also offers digital contrast, brightness, and saturation for color adjustment. it can be adjusted in yuv data. the sharpness control provides good effect for image enhancement. it also provides keystone function for projector application. 8.4.1 video de-interlaced with film detection and motion adaptive video processing unit equips a high quality de-interlacing algorithm to optimize the output progressive scan frame by recovering film sequence and compensating motion effect during the de-interlacing process. the motion estimation can evaluate both y/c data or y data by setting register. in motion compensation process, the sensitivity of the data estimation can be adjusted by register for lumina and chroma threshold. in film video, such as dvd movie, some duplicate fields are inserted into the interlaced video stream. original film sequence detection and recovery can produce a smooth progressive scan frame transition after de-interlaced. 8.4.2 up scale engine the up scale engine can scale up primary stream to higher resolution in high quality for output display. the AL260 adapts fir scaling engine that can do horizontal and vertical up scale independently. the primary stream picture can be either down scale to smaller size of picture or up scale to larger size of picture from original capture (input) picture for output, but it can not do both up and down scale process at the same time. consider to capture full picture of input data if the output resolution of primary stream picture is going to be enlarged. following block diagram illustrates the define registers of source primary stream window and destination up scale window.
AL260 ?2002,2003-copyright by averlogic technologies, corp. version b1.0 20 8.4.3 keystone up scale engine the AL260 can scale up the image in dynamic ratio which is good for lcd projector image correction. the projected images from the lcd projector sometimes show as figure due to the misalignment or cheap optics. the AL260 can up scale picture in dynamic ratios which are loaded from pre-stored at internal fifo buffers. the keystone is designed to compensate the distortions, such as figures following. 8.4 vou (video output unit) two independent on-screen-display (osd) windows provide overlay for a control menu, text, or caption on the output display. the AL260?s osd is very flexible in the way that the font, size, and display location are all programmable. the internal 2k byte sram provides storage for the osd information. the osd can be operated with only this
AL260 ?2002,2003-copyright by averlogic technologies, corp. version b1.0 21 internal sram or with an external rom to store font tables or even larger bitmaps. built- in 8bit programmable gamma look-up table for each input color channel for gamma correction. it may be used for rgb contrast, brightness and color temperature adjustments. dithering is performed to retain color resolution for lcd panels that support 18-bit color depths. AL260 provides digital video output interface that can be directly connected to 24bit tft lcd panel or dvi/lvds transmitters. it also provides analog video output which can support up to sxga resolution.
