本文针对用Intel 80系列标准模块直接连接到MULTIBUS而构成的各种紧耦合和松耦合多微机系统,提出了实时操作系统方案。方案采用了软硬件相结合的方法来统一管理多机中断。允许系统中任何一个任务向另一个任务发动通信。机器对于任务是透明的。允许微机台数可达七至八台。在紧耦合的多微机系统中,不论共享存贮器的分布情况如何,允许七台微机的任务之间以有息包方式交换信息。在松耦合的多微机系统中,则允许八台微机的任务之间逐字交换信息。对分散共享存贮器的紧耦合系统的多机通信模块在Intel MDS-231开发系统上进行了仿真。
In this paper, a series of real-time operating system solutions are proposed for various tightly coupled and loosely coupled multi-microcomputer systems formed by the direct connection of Intel 80 series standard modules to MULTIBUS. Program uses a combination of hardware and software to unify the management of multi-machine interrupt. Allows any one task in the system to communicate with another task. The machine is transparent to the task. Allow the number of computer up to seven to eight. In a tightly coupled multi-computer system, no matter what the distribution of shared memory, it allows packets to be exchanged between the tasks of seven computers. In loosely coupled multi-computer systems, the eight-computer tasks are allowed to exchange verbatim information. The multi-machine communication module for tightly coupled system with decentralized shared memory was simulated on the Intel MDS-231 development system.
