摘要
用“数据驱动”(Data-Driven)和“事件驱动”(Event-Driven)代替常规的“时间驱动”(Time-Driven)作为分布式实时控制系统执行软件的驱动机制,可以使系统中数据传输效率和系统的实时性都有较大的提高。本文所述的执行软件在这方面做了一些尝试,取得了较好的效果。
By using'Data-Driven'(DD)and'Event-Driven''(ED) instead of conventional 'Time Driven'(TD), as the basic mechanism in the design of Executive Software (ES)for distributed real-time control system, the bus load maybe decreased and the system efficiency maybe increased by the systems. The paper deals with some critical design issues of ES, such as bus access technique, system synchronization and data consistency etc. For the reasons of using DD and ED mechanisms in implementation and simplification of several hard problems, the overhead of ES and the load of cpu are greatly decreased.
