实时系统一般由几个并行过程或任务组成.每个任务是顺序的,利用在不同速度下运行的异步任务来获得并行性.这些任务需要时时相互通讯与同步.本文简要地介绍几种现有的软件设计方法并对它们如何适用于实时系统进行了研究.本文概述了实时系统的设计要求并描叙了称为DARTS(Design Approachof roal-timee System)的实时设计方法.以一个机器人控制器为例了来说明DARTS方法的使用.
Real-time systems are typically made up of several parallel processes or tasks, each of which is sequential and takes advantage of asynchronous tasks running at different speeds to achieve parallelism, which require constant communication and synchronization with each other.This article briefly introduces several existing And describes how they are applied to real-time systems.This paper outlines the design requirements of real-time systems and describes a real-time design method called DARTS (Design Approach of roal-timee System) .With a robot controller as Example to illustrate the use of DARTS method.
