32位微处理器在工业实时显控系统中的应用

Application of 32-bits Microprocessor for Industrial Real-time Display Control System

提出了一种基于32位微处理器MC68331的工业实时显控系统设计方案。实现了主微处理器和显控系统微处理器进行异步串行通信时抗干扰性能优良的电平转换电路设计,利用MC68331内部的SIM(系统集成模块)及GPT(通用定时器)模块配置外围扩展系统,最大限度地节省了硬件资源,降低了成本。

This paper presents a design scheme of real-time display control based on 32-bits microprocessor MC68331.We realized communication circuit with better anti-interference capability between main microprocessor and other microprocessor in the display control system,and extended the outer systematic configuration by sub-module SIM and GPT within MC68331, which can save the hardware resource and reduce cost to a large extent,Moreover.
