在采用多道程序设计的系统中，往往有若干个进程同时处于就绪状态，操作系统必须按照某种调度策略决定哪些进程优先占用CPU。本实验是在单处理机的情况下用优先权的调度策略实现处理机调度，以加深了解处理机调度的工作过程。-The introduction of multi-channel programming systems, often at the same time a number of processes in the ready state, the operating system must be according to some scheduling policy to determine which process preemption CPU. This experiment is the case of a single processor with priority scheduling strategy to achieve processor scheduling, processor scheduling in order to better understand the work process.
