中文摘要：

CPU模拟器能够提供一个了解计算机内部操作的入口，便于工程技术人员对所设计的电路进行验证，同时模拟器还是一个有效的教学工具．结合CPU电路执行一段程序的过程说明了利用Simulink构建X86CPU模拟器电路的方法，通过调用Simulink的子系统创建电路的模拟，去除多余的引脚，简化了电路，突出了使用Simulink模拟的高效性和准确性．

英文摘要：

CPU simulators can provide an entrance for understanding function within computer,often used by engineers to verify the correctness of the circuit. It is an effective teaching tool. With the example for CPU circuit executing a program, introduce a method that build X86 cpu simulator circuit using simulink, transferring the subsystem of simulink creates the simulation of circuit, by deleting redundant pins and simplifying circuit, it stands out the high efficiency and veracity by using simulink.
