32位微机实验系统的设计与开发

The Design of Experimental System for 32 Microcomputer

为了利用现有的微机原理实验箱进行32位微机原理实验教学,该文介绍了一种32位微机原理实验系统的设计方法,该方法通过微机系统内部PCI总线扩展出低速ISA总线接口信号,从而将微机系统内的部分资源引出并利用,对实验箱上的模块进行操作并进行实验。利用该实验系统可全面支持＂微机原理与应用＂及＂微机接口技术＂的各项实验内容。

In order to using the existing microcomputer experiment board to do experiments for 32 microcomputer,this paper proposes a method to design the experiment system for 32 microcomputer.In this method,the internal PCI bus in microcomputer system is expanded to the low-speed ISA bus,thus some of the resources within the microcomputer system can be used to do some experiments on the external experiment board.With the use of the experimental system,the experiments of the case ＂Microcomputer Principles and Applications＂ and the case ＂microcomputer interface technology＂ can be carried.
