本文介绍一种多微处理机系统的方案。它是通过一条处理机间总线把五台微处理机模块以紧耦合方式连接起来。通过硬件轮流优先电路的裁决逻辑来实现处理机间总线的争用。每台微处理机模块包括专用存储器和共享本地存储器。本系统的主要特点是一台处理机模块可以通过处理机间总线访问另一台处理机模块的共享本地存储器。本系统主要采用硬件方法,而尽量简化软件。 This article describes a multi-microprocessor system solutions. It connects five microprocessor modules in a tightly coupled manner through an interprocessor bus. The contention logic of the interprocessor bus is realized by the decision logic of the hardware priority circuits. Each microprocessor module includes dedicated memory and shared local memory. The main feature of this system is that a processor module can access the shared local memory of another processor module by processing the inter-bus. The system uses the hardware method, and try to simplify the software.
