【摘要】 指令集仿真器是进行芯片设计评估,系统软件设计开发以及计算机软硬件协同设计的不可或缺的工具。在DSP的硬件设计和后期算法开发中,指令集仿真器也同样是起着至关重要的作用。该文参考当前在指令集仿真领域比较先进的JIT-CCS和IS-CS仿真技术,吸取了各自的一些优点,提出了仿真策略,设计并实现了基于DSP3000的指令集仿真器HJS。为了兼顾仿真速度与精度的要求,HJS实现了指令精度和时钟周期精度两种级别的仿真。同时,在指令Cache和流水线的仿真上都做到了既尽可能与实际硬件相符,同时也兼顾执行效率。为评估DSP硬件设计、DSP算法的实现提供了很好的软件模拟平台。更多还原

【Abstract】 Instruction Set Simulation is a powerful tool for CPU design evaluation,system software development and co-design of hardware and software.This paper gives out its own simulation strategy,design and implement an instruction set simulator HJS based on DSP3000 with reference to modern simulation techniques of JIT-CCS and IS-CS.In order to meet the requirement of speed and performance,HJS achieves two-level simulation of instruction-accuracy and cycle-accuracy.It provides a good software platform for DSP design and DSP algorithms implementation.更多还原
