Multiple replacement policies have been proposed that attempt to predict future reuse distances from past access patterns, thus allowing them to approximate the optimal replacement policy. Some of the best performing cache replacement policies are ones that attempt to imitate Bélády's algorithm. See more In computing, cache algorithms (also frequently called cache replacement algorithms or cache replacement policies) are optimizing instructions, or algorithms, that a computer program or a hardware-maintained … See more The average memory reference time is $${\displaystyle T=m\times T_{m}+T_{h}+E}$$ where $${\displaystyle m}$$ = miss ratio = 1 - (hit ratio) $${\displaystyle T_{m}}$$ = time to make a main … See more One may want to establish, through static analysis, which accesses are cache hits or misses, for instance to rigorously bound the See more • Definitions of various cache algorithms • Caching algorithm for flash/SSDs See more Bélády's algorithm The most efficient caching algorithm would be to always discard the information that will not be needed for the longest time in the future. This optimal result is referred to as Bélády's optimal algorithm/simply optimal … See more • Cache-oblivious algorithm • Locality of reference • Distributed cache See more WebThe goal of a replacement policy is to try to remove the page least likely to be referenced in the immediate future. Two of the most common replacement algorithms used are the first-in, first-out (FIFO) and the least recently used (LRU). The FIFO algorithm selects for replacement the page that has been in memory the longest time.
