the v830 microprocessor is the first member of necs v830 tm family of 32-bit risc microcontrollers. the high-performance, low-power v830 microprocessor with dsp features and on-chip caches is ideally suited for low-cost embedded applications. the high processor bandwidth allows the v830 to target multimedia applications such as jpeg decoding and internet-based information appliances. dsp functionality is provided with a 32-bit hardware barrel shifter and a single-cycle, multiply-and-accumu- late (mac) instruction executing up to 200 million operations per second (mops). v830 ? 32-bit risc microprocessor specifications block diagram clock frequency: 33 to 100 mhz performance C 118 dhrystone mips C 214 mips/w 32-bit single-cycle mac instruction (200 mops) 32-bit external data bus 16-level maskable interrupts plus nmi power consumption: 550 mw at 100 mhz at 3.3 v 0.35-m cmos process technology 16k of instruction and data cache/ram 3.3 volts v dd 96ni-1053c (11/98) int a1-a31 be0-be3 intv0?ntv3 d0-d31 cs0-cs3 bh st0?t3 ready siz16b hldrq hldak asel bcyst r/w nmi v830 cpu core 50/33 mhz 100 mhz 50/33 mhz bclk cmode reset barrel shifter interrupt controller system registers 32-bit adder (with sum-of-products function) 32 general-purpose 32-bit registers instruction cache 4k instruction ram 4k data cache 4k data ram 4k write buffer (4 stages) clock controller bus interface unit
