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。
This article outlines the application of a dedicated dual microcomputer function distribution system in ship navigation automation. Distributed computer system due to the modular, powerful, good performance and other characteristics, to complete the larger and more complex tasks. A TRS-80 microcomputer and Z-80 single-board function of the distributed system, both to complete the real-time processing, control and other functions, but also to complete a large number of operations. For specific purposes, you can take advantage of existing software distributed in the stand-alone system, reducing system design costs and research cycles. Focus on introducing the system software to solve several problems: (1) system communication; (2) BASIC language program interrupt handling; (3) in the Z-80 machine interrupt handling.
