摘要
采用VLSI的实现方法设计了一种高速低功耗32位RISC微处理器(FDU32)。该处理器指令和接口均与ARM7TDMI兼容,通过采用新的流水线结构、冲突控制策略及低功耗的数据通路,使其在0.35靘 CMOS工艺条件下与传统ARM7TDMI相比,CPI减小11%,主频提高67%,MIPS提高87%,数据通路功耗降低46%,仅芯片规模略有增加。此外,设计中还采取了多项措施以保证芯片工作的稳定性和鲁棒性。该处理器功能已通过FPGA验证。
The design of a high-speed low-power 32-bit RISC microprocessor (FDU32) which is compatible with the ARM7TDMI in VLSI is presented. By using the new pipeline structure,hazard controlling strategy and low-power data path,11% reduction of CPI,67% improvement of clock frequency,87% enhancement in MIPS and 46% reduction in data path power can be achieved in 0.35靘 CMOS technology with only a little increment of the chip size. Furthermore,several methods are implemented to ensure the stability and robustness of the chip. The function of the processor has been verified by FPGA.
