演示了linux下的常用页面置换算法(FIFO,LRU,OPT,LFU,NUR),并计算了相应的命中率。程序用随机函数产生指令序列,然后变换成相应的页地址流。-demonstration of the commonly used algorithm replacement pages (FIFO, the LRU, OPT, LFU, NUR), and calculated the corresponding hit rate. Procedures used functions to generate random instruction sequences, and then converted into the corresponding page addresses flow.
