  2. Cache placement policies - Wikipedia

    en.wikipedia.org/wiki/Cache_placement_policies

    Cache placement policies are policies that determine where a particular memory block can be placed when it goes into a CPU cache.A block of memory cannot necessarily be placed at an arbitrary location in the cache; it may be restricted to a particular cache line or a set of cache lines [1] by the cache's placement policy.

  3. Cache replacement policies - Wikipedia

    The RRIP backend makes the eviction decisions. The sampled cache and OPT generator set the initial RRPV value of the inserted cache lines. Hawkeye won the CRC2 cache championship in 2017, [24] and Harmony [25] is an extension of Hawkeye which improves prefetching performance. Block diagram of the Mockingjay cache replacement policy

  4. Cache inclusion policy - Wikipedia

    en.wikipedia.org/wiki/Cache_Inclusion_Policy

    The merit of inclusive policy is that, in parallel systems with per-processor private cache if there is a cache miss other peer caches are checked for the block. If the lower level cache is inclusive of the higher level cache and it is a miss in the lower level cache, then the higher level cache need not be searched.

  5. Cache (computing) - Wikipedia

    Diagram of a CPU memory cache operation. In computing, a cache (/ k æ ʃ / ⓘ KASH) [1] is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere.

  6. Cache hierarchy - Wikipedia

    en.wikipedia.org/wiki/Cache_hierarchy

    This policy ensures that the data is stored safely as it is written throughout the hierarchy. However, in the case of the write back policy, the changed cache block will be updated in the lower-level hierarchy only when the cache block is evicted. A "dirty bit" is attached to each cache block and set whenever the cache block is modified. [27]

    A browser's cache stores temporary website files which allows the site to load faster in future sessions. This data will be recreated every time you visit the webpage, though at times it can become corrupted. Clearing the cache deletes these files and fixes problems like outdated pages, websites freezing, and pages not loading or being ...

  8. CPU cache - Wikipedia

    en.wikipedia.org/wiki/CPU_cache

    A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.
