WebAbstract—Block replacement algorithms to increase hit ratio have been extensively used in cache memory management. Among basic replacement schemes, LRU and FIFO have been shown to be effective replacement algorithms in terms of hit rates. In this paper, we introduce a flexible stack-based circuit which can be employed in WebThe second chance algorithm (which some people call the clock algorithm) works just like FIFO, but it skips over any pages with the use bit set (and clears the use bit). ... Because processes share physical memory using a heuristic replacement algorithm instead of acquiring and releasing it, the total amount "in use" is a bit of a fuzzy concept

WebIf we can clearly see access patterns and can predict future required pages, then 'optimal page replacement' is the best. As mentioned by sanjay in the other answer, it minimizes page faults. If the pattern cannot be predicted, LRU could be decent for most of the real-world workloads. But some work-load may show FIFO outperforming LRU. WebJul 30, 2024 · Cache replacement algorithms are used to optimize the time taken by processor to process the information by storing the information needed by processor at that time and possibly in future so that if processor needs that information, it can be provided immediately.
