可编程系统器件PSD在80C196KC单片机系统中的应用

The Application of the PSD in 80C196KC MUC System

本文介绍了可编程系统器件(Programmable System Device,简称PSD)和单片机80C196KC组成的某车辆单片机控制系统的设计。通过将PSD引入到该控制系统中,将原系统中的RAM、ROM、Flash及相关的译码电路都由PSD来实现,大大的简化了硬件电路的设计与调试,为系统的功能的不断完善及控制任务的增多提供了基础。研究表明基于PSD技术的设计是简化硬件电路设计、提高系统可靠性和实现灵活配置的有效方法,具有较高的实用价值。

A MCU control system which is composed by PSD and 80C196KC is introduced in this paper. The design of the hardware and to debug the hardware is predigested by using the PSD which replaces the RAM, ROM, Flash and the logics in the old system. By using this method, we have the good condition to improve the function of the system and also we can use the system to deal with more tasks. By our studying, it is an effective method and well worth to design systems based on PSD, which can make the hardware of the system predigesting, improve the reliability of the system and realize the flexible configure of the system.
