最近几年,分布多处理机系统的设计受到极大关注。随着LSI 和 vlsi 的出现,可以设计成本低,效能高的多微处理机模块,作为构成分布系统的基本单元使用。在分布系统的设计中,需要解决下列几个问题:(1)每个模块的内部结构,(2)模块间的信息交换处理,(3)通过分布邮箱(mailbox)的信息交换,(4)分布计时和控制,(5)分布优先级判定和死锁检查。该文将讨论这些问题,提出实际的解决方法,并进行简单的性能分析。
In recent years, much attention has been devoted to the design of distributed multiprocessor systems. With the advent of LSIs and vlsi, it is possible to design a multi-microprocessor module that is low in cost and high in efficiency and used as a basic unit constituting a distribution system. In the design of distributed systems, the following problems need to be solved: (1) the internal structure of each module, (2) the exchange of information between modules, (3) the exchange of information through distributed mailboxes, (4) Distributed timing and control, (5) distributed priority determination and deadlock checking. This article will discuss these issues, propose practical solutions, and perform simple performance analysis.
