本文简要地分析了一个在带有共享存贮器的多主总线环境下实现的机间通信协议(以下简称MIP)。实现该协议的MIP设施以接口形式附着在一些操作系统之上,使得两个不同操作系统之间通信转变为相同的MIP设施之间的通信。从而方便了用户,提高了透明度;同时,由于它采用了消息传递方式通信,所以它适应范围广,可靠性高。文章最后一部分在分析MIP基础上,提出了一种以设备和通道为依据进行数据结构划分的新技术,它对提高多机系统实时性具有一定的实际意义。
This article briefly analyzes an inter-machine communication protocol (MIP) implemented in a multi-master bus environment with shared memory. MIP facilities that implement this protocol are attached as interfaces to some operating systems so that communications between two different operating systems translate into communications between the same MIP facilities. Thus facilitating the user and improving the transparency; at the same time, because it uses the messaging method of communication, it has wide adaptability and high reliability. Based on the analysis of MIP, the last part of the article proposes a new technology for data structure division based on equipment and channel, which has some practical significance to improve the real-time performance of multi-machine system.
