摘要
ＰＣ系列机面向智能测控设备的通讯控制器（通讯卡）是很多应用系统中的关键环节，它起着上、下两级ＣＰＵ之间的桥梁作用。在工业集散系统和计算机集成制造系统（ＣＩＭＳ）中，它负责管理工作站和下位机（现场智能测控设备）之间的信息传输。本文介绍了用８０９８单片机作ＣＰＵ实现的智能通讯控制器，重点分析了双端口存贮器ＩＤＴ７１３０作为ＫＣＰＵ之间信息交换的实现方式，设计新颖紧凑实用。
The communication controller of PC computers connected with intelligent device is the impor-tant device, it acts as the bridge of intellignt device and PC workstation. The communication controller is also important in Computer Integrated ManufaCTURING System. This paper discusses the design of interlligent PC communication controller used the new integrated circuits of 8098 micropocessor, CMOS DUAL-PORT TAM IDT7130, especially discusses the exchange data method of two CPU used DUAL-PORT RAM.This design is new, compact and pratical.
