基于PCI总线的微机接口实验仪设计与实现

Design and Implementation of an Educational System of Microcomput er Interface Based on PCI Bus

提出了一套全新的微机接口实验仪。该实验仪利用PCI主模式控制芯片Plx9054在PCI总线上扩展出一个8位教学用微机实验总线(E-Bus),并在该总线上设计了一个EDA的开发平台和一套软件开发包。学生即可以利用该E-DA平台和软件开发包在E-Bus上设计各种PC机接口。该文首先描述了E-BUS的扩展方法和EDA开发平台的组成原理,然后给出了一个键盘接口的例子对实验步骤做了详细描述,最后与国内同类产品进行了比较。

An advanced microcomputer interface educational system is presented in this paper.It includes an8-bit edu-cational bus(E-Bus)expanded from PCI bus with plx9054and an EDA developing platform based on E-Bus.Students should make use of such a platform to implement their own computer interface design and test on E-Bus.The frame of this system is firstly been introduced,then a PC keyboard example is given later to explain details of the experiment steps.At last,a comparison between this device and its contemporary is made.
