摘要
嵌入式ＣＰＵ已成为ＳＯＣ设计的热点。异常处理是ＣＰＵ设计中最关键的部分。介绍嵌入式ＣＰＵ异常处理的一般机制，并在此基础上设计３２位ＣＰＵ的异常处理模块，给出了仿真结果，并讨论了其方便的可扩展性。
Embedded CPU has been a focus of SOC design. Exception processing circuit is the most crucial module in CPU designs. In this paper, the principles of exception processing are introduced first. Then an example of exception processing in 32-bits CPU is presented with some simulation results. The flexible expansibility of the example is discussed finally.
