摘　　要：嵌入式实时操作系统VxWorks提供的中断处理机制中断延迟小,应用编程方便。MPC860是目前在网络与通信领域应用非常广泛的一款微处理器芯片。论文详细分析了VxWorks及MPC860的中断处理机制,阐述了中断处理应用编程的过程,并给出了应用实例。Interrupt handling mechanism under VxWorks is of high performance in reducing interrupt latency and programming in application. MPC860 is a versatile one-chip integrated microprocessor which particularly excels in both communications and networking systems. In this paper, the interrupt handling mechanisms of both VxWorks and MPC860 are analyzed in detail. Then, the process of interrupt handling programming is described. At last, an example in application is provided.
