共享RAM多微机系统

A Multimicrocomputer System with Shared RAM

本文提出一种以共享RAM为信息交换界面的多微机系统,着重讨论了总线仲裁电路、总线隔离电路的工作原理和工作时序。该电路结构具有联机实时性强、抗干扰能力强、可扩充性好等优点,用于金华造漆厂中间罐区微机集散系统中运行稳定。

This Paper puts forward a multimicrocomputer system with shared RAM as message—switching interface. The operating principles and sequence of bus arbitrating circuit and bus isolating circuit are discussed. The system, characterised by its capacity in online realtime operation, in anti—interference, and in open—endedness, turns out to work steadily when tested in Jinhua Paint Factory.
