常见置换算法有随机淘汰算法(Random Glongram)、轮转法(Round Robin)和先进先出(FIFO)、最近最久未使用页面置换算法和理想型淘汰算法OPT(Optimal Replacement Algorithm)。本次所设计的模拟系统根据题目要求利用随机淘汰算法,先进先出算法和理想型淘汰算法进行页面替换,详细算法原理如下: 随机淘汰算法:在系统设计人员无法...
either after a write or when a read buffer is full. That uses a simple state machine and a try-lock to coordinate, so the eviction policy does not suffer from lock contention. As BP-Wrapper describes itself, it"(almost) eliminates lock contention for any replacement algorithm without requirin...
