摘　　要：MPC5634中断控制器有软件中断向量模式和硬件中断向量模式2种中断处理方式。为了验证2种不同模式实现过程的差异性,对MPC5634嵌入式微处理器的中断控制器的处理机制进行研究,并运用Codewarrior编译器及示波器作为调试工具,MPC5634开发板作为调试平台,对中断控制器的2种模式的中断处理过程进行了分析,通过观察硬件向量模式和软件向量模式进入中断异常句柄的顺序,验证了2种中断模式的区别。MPC5634 interrupt controller has 2 inten＇upt processing ways, e.g. soflware interrupt and hardware interrupt. In order to show differences of Embedded micro controller MPC5634 in two different interrupt ways, the processing way in the embedded micro controller is studied, on the basis of MPC5634 used as the development platform, the Codewan＇ior compiler and oscilloscope as debugging tools to analvze interrupt processes of controller in two different processing ways is described in this paper. The difference is presented through observing the sequence come into the exception handler in software interrupl way and hardware interrupt way.
