基于通用抽象接口的CPU仿真

CPU Simulation Based on Abstraction Interface

为实现对微处理器的仿真,基于虚拟机(Virtual Target Machine)方法设计出了一组微处理器抽象接口(Abstraction Interface).通过实现该组接口就可以建立相应的后端虚拟机,其仿真尺度包括了指令单步运行和对时序模拟、汇编代码的支持,并可根据前端调试命令而实现与宿主机平台无关的软件仿真.

This paper proposes a set of common abstraction interface for the micro - processor simulation based on virtual target machine method. By means of the set of common abstraction interface, the backend of processor simulator can be set up and its simulation standards include the single - step, the display of time - order and the debug in assembling language level. The front - end simulation software could be independent of each other.
