They must include: - Total cache size. - Block size. - Associativity (direct-mapped, set-associative). - Unified vs. split I- and D-caches. - Write back vs. write through. - Write allocate vs. write no allocate. WebDirect Mapping – This is simplest mapping technique. Here it maps each data block of RAM into only one possible cache data line. The old block is removed if a line is previously taken up by a memory block, when trying to load new data block. An address space has two field i field and a t field.

An Empirical Study for Multilevel Cache Associativity

WebWhat differentiates an associative cache from a directly mapped cache is the ability to arbitrarily associate data objects. Associative caches may freely associate data items, unlike directly mapped caches. The capacity to flexibly associate data items sets a truly associative cache apart from a directly mapped cache as the key differentiator ...
