摘　　要：针对80x86外部中断发生的随机性而带来的中断过程突发事件比较多等问题,设计了由8086CPU、可屏蔽中断电路、非屏蔽中断电路和显示电路组成的基于Proteus的80X86中断控制电路,在Proteus仿真平台下完成了软、硬件电路的调试,使用激励信号源实现了图表的交互式动态仿真,采用硬件断点和调试弹出窗口方式加快了程序调试的效率。仿真结果表明,使用Proteus分析80X86的外部中断过程,可将复杂、抽象的中断直观地展现出来,有助于学生更好的理解80X86的外部中断过程,提高分析问题和解决问题的能力。To solve the problem of the randomness of 80X86 interrupt process execution,a interrupt circuit based on Proteus was established by mainly using 8086CPU,shielded interrupt circuit,non-maskable interrupt circuit and indication circuit. It was completed the debugging of the hardware circuit and software circuit under the Proteus simulation platform. The interactive dynamic simulation for simulation chart was realized by using the excitation source provided in Proteus. The hardware breakpoint and debugging pop-up window were adopted to accelerate the debugging efficiency. Simulation result shows that the analysis of external interrupt processes for 80X86 by Proteus not only can visualize the interrupt process of complex abstractions but also can help scholars better understanding of 80X86 external interrupt process and improve students of ability to analyze and solve problems.
