功能分布式双微机系统用于船舶自动导航

本文概述一个专用双微计算机功能分布系统在船舶导航自动化中的应用。分布式计算机系统由于具有模块化、功能强、性能好等特点,能完成较大、较复杂的任务。一个TRS-80微型机和Z-80单板机组成的功能分布式系统,既能完成实时处理、控制等功能,又能完成大量运算。对于特定的目的,可以利用分布系统各单机已有的软件,降低系统设计成本和研究周期。 着重介绍本系统软件主要解决的几个问题:(1)系统的通信;(2)BASIC语言程序的中断处理;(3)在Z-80机中处理中断的方法。

A FUNCTION-DISTRIBUTED TWO-MICROCOMPUTER SYSTEM IN APPLICATION TO THE SHIP AUTO-NAVIGATION

This paper describes a function-distributed two-microcomputer system used in the auto-navigation of ship, which is capable of completing more complex tasks due to its modularization and good performance. This system, consisting of a TRS-80 microcomputer and a Z-80 one-board microcomputer, was designed to meet the requirements such as real-time processing, real-time control and time-consuming calcu-lation. For the purposes above, the existing sorfware resources of the microcomputers in the system have been utilized to reduce the cost of design and the period of research.Emphasis has been laid on the issues the design of the system mainly concerned with:(1) The communication in the system. (2) The processing of the interrupts with in BASIC languahe program. (3) The method of processing interrupts at the Z-80 one-board microcomputer.
