SPARC体系结构的操作系统仿真器实现方法研究

Researching of Operating System Simulator Based on SPARC Architecture

在CPU的研制阶段通常也要同时进行操作系统的开发，为在新型CPU问世之前运行和调试目标操作系统，就必须开发支持操作系统功能的CPU仿真器。文章针对一种正在研制的基于SPARC体系结构的CPU，提出了操作系统仿真器的两种实现方案，然后对其中一种相对可行的方案进行了深入研究，并总结了开发过程中解决的一些实际问题。

： While developing CPU，O．S．should be also developed at the same time．In order to run and test O．S．before CPU is developed，It must have a software that emulates the CPU behavior，this software is called O．S．simulator．This paper raises two kinds of simulation strategy of a developing CPU based on SPARC architecture，and then gives a more detailed research on a relatively practical strategy．Some developing experience is also enclosed in this paper．
