摘要
在微处理器设计中 ,为了系统级软硬件协同仿真 ,在后端设计前必须采用硬件仿真器对设计进行系统验证 为此 ,采用FPGA设计 32位RISC流水线结构微处理器的硬件仿真器 此设计主要包括以下特点 :采用内存管理单元(MMU)可以实现虚拟地址管理 ;包括片上Cache ,其中包括指令Cache(I Cache)和数据Cache(D Cache) ;采用标准SYSAD接口设计 ;包括片上乘除处理单元 (MDU) ;实现精确异常处理 设计采用XILINX公司的xc2v2 0 0 0实现 ,其工作频率为
During the microprocessor design, in order to do the software/hardware co-simulation, the hardware simulator of the microprocessor must be designed before the back-end design of the chip. The hardware simulator of a 32-bit RISC pipeline microprocessor, which is implemented with FPGA, is provided in this paper. Its primary features include: on-chip memory manage unit (MMU), which is used to realize virtual memory management; on-chip primary cache, which includes instruction cache and data cache; standard SYSAD system interface; on-chip multiply/divide unit (MDU); precise exception handling. The hardware simulator is implemented with the FPGA xc2v2000 of the XILINX company and its work clock frequency is 30MHz.
