摘要
进程可以被理解成活动的程序,每个进程是相互分离的实体,是CPU正在运行的一个特定程序。因为进程能处理同时发生的多个事件,所以它对嵌入式系统的设计来说是非常重要的,介绍通常只有一个CPU的嵌入式操作系统如何让每个进程只能连续的运行很短的时间并使每个进程认为只有自己在运行的机理和一个设计时没有引入进程概念的实时嵌入式系统是非常危险的。
The proceeding can be regard as the movable program, each proceeding is mutual separate entity and the special program processed by CPU. The proceeding can process multi-event at the same time, so it is very important for the design of the embedded system. This paper introduces the principle which is how to make each proceeding only process in a very short time continuously and make it consider it only processes itself in the embedded system with only one CPU, and it is very dangerous that one design of real-time embedded system without the proceeding concept.
