2. Cache performance measurement and metric - Wikipedia

   en.wikipedia.org/wiki/Cache_performance...

   A CPU cache is a piece of hardware that reduces access time to data in memory by keeping some part of the frequently used data of the main memory in a 'cache' of smaller and faster memory. The performance of a computer system depends on the performance of all individual units—which include execution units like integer, branch and floating ...

3. 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.

4. Cache (computing) - Wikipedia

   en.wikipedia.org/wiki/Cache_(computing)

   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.

5. Cache hierarchy - Wikipedia

   en.wikipedia.org/wiki/Cache_hierarchy

   In the case of a cache miss, the purpose of using such a structure will be rendered useless and the computer will have to go to the main memory to fetch the required data. However, with a multiple-level cache, if the computer misses the cache closest to the processor (level-one cache or L1) it will then search through the next-closest level(s ...

6. Cache prefetching - Wikipedia

   en.wikipedia.org/wiki/Cache_prefetching

   Cache prefetching can be accomplished either by hardware or by software. [3]Hardware based prefetching is typically accomplished by having a dedicated hardware mechanism in the processor that watches the stream of instructions or data being requested by the executing program, recognizes the next few elements that the program might need based on this stream and prefetches into the processor's ...

7. Translation lookaside buffer - Wikipedia

   en.wikipedia.org/wiki/Translation_lookaside_buffer

   The TLB is a cache of the page table, representing only a subset of the page-table contents. Referencing the physical memory addresses, a TLB may reside between the CPU and the CPU cache, between the CPU cache and primary storage memory, or between levels of a multi-level cache. The placement determines whether the cache uses physical or ...
