快速双CPU并行通讯接口

High Speed Parallel Interface Between Two CPU

本文提出一种新型的,快速双CPU并行接口电路。这个接口电路的特点是:1、通过公共随机存储器交换信息,客量大、速度快。2、每个CPU各自独立形成子系统,在交换信息时,可独立工作,互不影响。3、采用通用集成块,易于制作,价格低。这个接口电路可用于主、从CPU系统;主CPU系统与智能化终端的连接;主CPU系统与智能化传感器的连接;以及分布式多CPU系统。

In this thesis, new high speed parattet interface between two CPU was given. The interface has some characters shown as follow: 1,Throngh common randam access menory two CPU interchange their information. It have large votume and high speed. 2,Every CPU form a sub-system, seperately. When they interchange their information, each one can operate independently and no inftuence from each other. 3,We can use common IC to Consist of this interface convenientty and cheapty. This interface can be used in principal and sabordinate CPU systems; prin cipat CPU system and intettegent terminat, principat CPI and intettegent sensor, or spread CPU systems.
