利用现有八位微处理机,发展多微处理机系统是当前微处理机应用开发的一个重要途径。本文讨论机间互连结构问题。互连结构必须尽可能简单,以适应微处理机体积小、成本低的特点。因此,接口元件应选用大规模集成电路。在微处理机间距离较近或要求较高传输速率时,可采用紧密耦合、并 The use of the existing eight microprocessors, the development of multi-microprocessor system is an important way of microprocessor application development. This article discusses the inter-machine interconnect structure issues. The interconnect structure must be as simple as possible to accommodate the microprocessor’s small size and low cost. Therefore, the interface components should use large scale integrated circuits. Tight coupling can be used when the distance between microprocessors is close or when higher transfer rates are required
