设计一个按优先数调度算法实现处理器调度的程序。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。本实习模拟在单处理器情况下的处理器调度，帮助学生加深了解处理器调度的工作。-Design a number of priority scheduling algorithm processor scheduling procedures. The introduction of multi-channel programming systems, often at the same time a number of processes in ready state. When the number is greater than the number of processors in place when the process, they must follow the process of a strategy to decide which priorities take up processor. This practice simulation in the context of a single processor processor scheduling, processor scheduling to help students better understand the work.
