A benchmark of it is its miss rate, which is roughly inversely proportional with its size.
This device is first used in Model 85 of the IBM System/360 product line. It is often used hierarchically, with architectures ranging from strictly inclusive to exclusive. They can range from fully associative over N-way associative to direct mapped, with the fully associative versions often smaller in size and direct mapped versions larger because of production cost issues. A benchmark of it is its miss rate, which is roughly inversely proportional with its size. Replacement of data can be least recently used for the direct mapped versions, but is often random for fully associative versions. Modern CPUs have several levels of it, ranging from L1, L2 to sometimes even L3, and it can be several MB in size. FTP, name this device used to store temporary data for faster write and retrieval.
