多微处理机系统与单微处理机系统或小型计算机相比,有如下特点:(1)通过分散功能或分散负载来提高处理速度、处理能力及吞吐量,而又比较经济.(2)充分利用模块化的优点,不仅能解决动态任务再分配,而且易于扩展,从而提高了适应性和灵活性.(3)便于分隔故障、独立自检,实现在线或离线重返.或配备专用故障诊断处理机,并提供设备,确保系统的高可靠性.对多微处理机系统可从不同的角度进行分类.1.控制方式
Compared with a single microprocessor system or a small computer, the multiprocessor system has the following features: (1) It is more economical (2) to improve processing speed, throughput and throughput by decentralizing functions or distributing the load (2) Utilize the advantages of modularity, not only to solve the redistribution of dynamic tasks, and easy to expand, thereby enhancing the flexibility and adaptability. (3) to facilitate the separation of faults, independent self-test, online or offline to return or equipped with dedicated fault diagnosis Processor, and provide equipment to ensure the high reliability of the system. For multi-microprocessor system can be classified from different angles .1 control method
