高校计算机学院操作系统课程关于进程通信的程序范例

1)  超级可以移植性，与CPU无关，几乎任何支持C语言编程的CPU都可以用！（本文仅仅以51单片机为例而已，但实际上可以任意移植） 2)  小之又小， 原理很简单，一看就懂。 3)  省之又省， 可以说对RAM和ROM省到极致。 4)  取protothread之精华，将定时器与状态机和伪线程语法融合到一个框架，任务函数可以有两种写法。 5)  基于定时器触发，调度效率高，最大化减少无效的代码运行时间。

采用静态优先数的方法，编写一进程调度程序模拟程序，进程状态为就绪、运行、阻塞三种。模拟程序只对你所设置的“虚拟PCB”进行相应的调度模拟操作，即每发生“调度”时，显示出当前“PCB名字”、优先数、运行时间等，而不需要对系统中真正的PCB等数据进行修改-priority number using the static method, the preparation process of scheduling a process simulation program, the process in place for the state, running, blocking three. Simulation program only right you have set up a "virtual PCB" accordingly scheduling simulation operation, that is, each occurrence "Dispatch" shows that the current "PCB name" priority number, running time, without the need for a real system, such as PCB data changes
