Cache replacement policies
WebAug 3, 2011 · In the replacement policy the most important factor is the number of associations (or ways). A direct map cache (1 way), directly correlates (all most always) with the low order bits of the address (the number of bits specify the size of the cache) so a 32k cache would be the lower 15bits. WebTechniques for performing cache operations are provided. The techniques include tracking performance events for a plurality of test sets of a cache, detecting a replacement …

WebJun 19, 2024 · Cache Replacement Policies. This book summarizes the landscape of cache replacement policies for CPU data caches. The emphasis is on algorithmic issues, so the authors start by defining a taxonomy that places previous policies into two broad categories, which they refer to as coarse-grained and fine-grained policies. Web12.3.2 CACHE LINE REPLACEMENT POLICIES. On a cache miss, the cache controller must select a cache line from the available set in cache memory to store the new information from main memory. The cache line selected for replacement is known as a victim. If the victim contains valid, dirty data, the controller must write the dirty data from …

WebMar 1, 2014 · Cache operations can also be pseudo-random such as random replacement policies, meaning the cache behavior is not entirely predictable. Reverse engineering effort can be onerous and only reveals ... WebWe study the performance of a family of cache replacement algorithms. The cache is decomposed into lists. Some of these lists can be virtual in the sense that only meta-data are stored in those lists. An item enters the cache via the first list and ...
WebHowever, temporal locality exploited by the cache is a function of both the replacement policy and the size of the working set relative to the available cache size. For example, if a workload frequently reuses a working set of 2 MB, and the available cache size is 1MB, then the LRU policy will cause all the installed lines to have poor temporal ...
