To improve the performance of a cache memory in terms of hit ratio and good response time system needs to employ efficient page replacement policy. And all replacement of pages has been occurred in cache memory. Page replacement algorithm decides which memory pages to page out when a page of ...

The most common page replacement algorithm and deallocation policy is based on the least recently used (LRU) principle. This principle indicates that the least recently used page is most likely to stay that way for the foreseeable future and, therefore, is a prime candidate to be removed and ...
