摘　　要：X86系列的CPU及其系统一直是"微机原理"课程的主流内容,其中中断是此课程的核心部分。目前,核心实验仍然是采取使用真实硬件进行实验的方式,但这种方式也带来实验项目受限,元器件易损坏等问题。随着Proteus对8086系列的CPU提供仿真功能,很多高校也开始将X86系列的微机原理实验向上移植。仿真实验便于实验内容扩展,便于学生自行实验,没有实验场地约束,破解了实验时间、地点的难题。仿真实验毕竟和物理实验有所差异,有不够完善之处,在移植过程中,实现中断的8259实验出现了一些问题。本文就此问题进行了研究和实验,剖析了产生问题的原因,并给出了多种解决问题的方法。X86 CPU and its interface system are popular in ＂ Computer Principle＂ course,and interrupt is one of the most important contents. Now,physical experiment is still the main method,but experiment items are limited and the electrical components are easy to be damaged. Many universities are doing simulation experiments on Proteus because it provides the simulation of 8086 CPU. Experiment item is easy expanded by simulation,and students can do it by themselves. The experiment time and location are flexible. Simulation experiments still have a few differences with physical experiment,and are not very perfect. There are still some problems with 8259 interrupt experiment. Some studies and experiments have been done on this problem. The analysis of the causes and solutions of the simulation are presented.
