弗吉尼亚大学的微计算机试验室目前正提供一种试验微计算机网络,设计这种网络对分布式处理控制系统的可能性进行试验。不采用传统的计算机结构,诸如单个的、大型的、快速的微计算机系统,来执行必要的系统控制功能,而是由用户划分这些功能,再由这种网络把用户分配到无数个基于微处理机的控制部件中,每个这样控制部件可以受网络动态控制,起一个半独立的微处理机的作用,起一个 I/O 设备控制器的作用,或者起一个与网络主 CPU 一起并行运行的从属 CPU 的作用。系统的总目标是:提高处理机的独立性,增加冗余度、动态重构、以及降低成本。
The Microcomputer Laboratory at the University of Virginia is currently providing a pilot microcomputers network designed to test the possibility of distributed process control systems. Rather than using traditional computer architectures, such as single, large, fast microcomputer systems to perform the necessary system control functions, these functions are divided by the user, which in turn distributes the user to countless microprocessor-based microprocessors Machine control unit, each such control unit can be dynamically controlled by the network, acting as a semi-autonomous microprocessor, as an I / O device controller, or as a network controller running in parallel with the network host Slave CPU role. The overall goal of the system is to increase processor independence, increase redundancy, refactor dynamically, and reduce costs.
