嵌入式实时操作系统VxW0rks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 VxW orks is ofhigh performance in reducing interrupt latency and programmingin applicaTIon， MPC860 is a versaTIle one—chip integrated mi—croprocessor which parTIcularly excels in both communicaTIonsand networking systems． In this paper， the interrupt handlingmechanisms of both VxW orks and M PC860 are analyzed in de—tail．Then，the process of interrupt handling programming is de—scribed．At last，an example in application is provided．
