计算机硬件虚拟仿真实验教学系统设计

摘要

The computer hardware experiment teaching has high requirements in the hardware facilities,and it has the disadvantages of high cost,high loss and low reuse rate.Based on these problems,this paper uses C/S mode,and combines with virtual instrument technology,the MySQL database and Visual Basic to build the basic architecture of the system.At the same time,using object oriented technology and component technology,it realizes the development of virtual components and virtual devices,solves the key problems of system design.The 8254 experiment is takne as an example to verify the effectiveness of the system.%计算机硬件试验教学对于硬件设施的要求较高,且存在高成本、高损耗及低重复利用率的弊端.针对此,采用C/S模式,并结合虚拟仪器技术、MySQL和Visual Basic等搭建了系统基本架构.详细阐述了系统设计思路、结构及功能,同时,以虚拟元器件及设备的开发以组件技术和面向对象技术为支撑,解决了系统设计的关键难题,并以8254实验为例,验证了系统的有效性.
