操作系统——动态优先级调度算法源代码

说明：  操作系统——动态优先级调度算法源代码，多道系统中多进程并发执行，为了提高系统性能解决进程死锁问题，进程的优先级是动态变化的。正在执行的进程优先级会随时间降低，而挂起的进程或等待的进程的优先级会逐渐升高，这样就解决了操作系统中一个地优先级程序长期占据cpu，而高优先级进程却迟迟不能得到处理。
(operating system-- Dynamic priority scheduling algorithm source code, multi-channel system more complicated implementation process. To enhance system performance Deadlock settlement process, the priority process is a dynamic change. The process is the implementation of priority will be reduced over time, and duration of the process, or wait for the process priority will be gradually increased, this would resolve the operating system to a long-term priority procedures occupy cpu, while high-priority process still could not be processed.)
