摘要
计算机应用于实时控制系统中之关键问题是组成最佳的硬件系统和软件系统。即计算机系统。本文对系统设计两个重要部份:中断系统的原理及接口电路的程序设计作了详细的讨论,并通过许多实例来说明如何根据系统工程提出的问题来组成所需的系统。(包括系统软件的组成,系统的主程序和中断服务子程序的设计),实例中给出的程序均在TP801微机上通过了模拟、仿真试验,具有很大的真实性和可移植性,对于不同的机型只要清楚对应的指令系统即能顺利的实现相应的软件设计。
The important problem of computers used in the real-time control system is how tomake up the optimal hardware system and software system, that is, the computer system. Inthis paper, two important parts of the system design——the theory of interrupt system andprogramming design of the interface circuit are dissused in detail, and then according to manyexamples the paper explains how to make up needful systems based on the system engineer-ing. The programs given in the examples have got through analogue simulation in microcom-puter TP-801 with the great truthfulness and transplantation.
