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。当就绪状态进程个数大于处理器数时，就必须依照某种策略来决定哪些进程优先占用处理器。本实验模拟在单处理器情况下处理器调度，帮助学生加深了解处理器调度的工作。-The introduction of multi-channel programming system, often at the same time there are a number of processes in a state of readiness. When the ready state of the process when the number is greater than the number of processors, a strategy must be in accordance with the process of priority to determine which processor occupancy. Experimental simulation of the processor in a single processor scheduling cases to help students gain a better understanding of the work of processor scheduling.
