  摘    要
 “虚拟实验平台”主要采用以“软”代“硬”和“虚”、“实”结合的设计思路，强调实用性，以最大限度地仿真真实的实验环境。主要实现了“专用实验台”的虚拟化，将它“搬”到了“微机”的显示器上，而原有在微机上的实验操作环境和方法仍然保持不变。系统还提供必要的测试仪器和工具（如示波器等），以便在实验调试时能够对运行结果进行监视或测量，如输出电平或波形，这种虚拟的测试仪器和工具也在界面和操作方面做到了尽可能的逼真。本文介绍了该虚拟试验平台的整体功能特点，主要介绍了8088CPU的结构，工作方式，以及如何用VC实现这些具体功能的编程方法。并加入了一些程序片段，对完成工作中遇到的困难也做了些总结。

Implementation of simplified model 8088 CPU’s Logic Function
Abstract
"Virtual platform" principal use "soft" to instead  of "hard" and "superficial", "real" combination of design ideas, emphasize practicality, to maximize the simulation of the real environment. Major implementation of the "exclusive Experimental Station," the virtual, it will be "moved" to the "PC" display, The original PC in the lab environment and methods remain unchanged. The system also provides the necessary test equipment and tools (such as oscilloscopes, etc.) Experimental testing in order to be able to run when the results of surveillance or measurements, such as the output level or waveform, This virtual testing equipment and tools also interface and the operation done in a realistic as possible. This paper introduces the Virtual Test platform overall features, mainly on the structure of the 8088 CPU, work methods, and how to use VC these specific functional programming method. And the inclusion of some procedures footage completed work on the difficulties encountered also made some conclusion.
Key words: virtual experement platform;8088CPU8; VC; encapsulation;register;port
