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 become a hot SOC design. Exception handling is the most critical part of CPU design. The general mechanism of embedded CPU exception handling is introduced. Based on this, a 32-bit CPU exception handling module is designed. The simulation results are given and their conveniences are discussed.
