高速并行多处理器系统原理及方案

当前,计算机应用领域对计算机的运算处理速度要求越来越高,而提高单机系统的处理能力是有限的,同时系统成本也会很高。因此并行处理技术成为解决这一矛盾的有效方法之一。并行处理系统从硬件角度采看,基本可分为两类;基于低信道容量网络的多计算机系统。这类系统多用于各结点信息藕合比较小、实时性要求不高的松散藕合系统。另一类即是紧藕合的多处理器系统。本文介绍一种已工程实用化了的紧藕合实时多处理器系统。该系统为研究多处理系统的并行算法、任务的实时划分、调度管理等关键技术提供了一个良好的硬件平台及软件环境,该系统可广泛用于要求迭代速率非常高的实时控制与实时仿真系统。

The Scheme and Principle of A High-Speed Parallel Multiple Processor System

As the development of the engineerings and technologise,higher speed of the computer system is being reguired.But,as we know,it is difficult to get a high processing speed in single processor system, and is also limited.Parallel processing technology is one of the efficient way to overcome these difficulies.The parallel processing technology has two different types in hardware structure.One is so called multiple computer system,which is composed of many independent computers and linked by a low data transfer rate network.In anther words ,it is a loosely-coupled system.Another is mutiple processor system,which is a tightly-coupled system. In this article we will introduce a multiple processor system which has been used in some control and simulation systems. And this system gives us a good environment to study some key technologise of parallel processing ,such as parallel scheduling ,parallel task spawning,etc.
