We extend this design with message passing among processors in a non-uniform memory architecture (NUMA).

CS 211: Computer Architecture Cache Memory Design

WebDec 15, 2024 · Verilog Hardware Description Language is used to design cache memory which involves direct mapping and set associative cache. Further set associative cache involves two-way, four-way and eight-way. In this design of cache memory architecture, the mapping technique can be varied using controller unit. To increase accessing speed … Web•Fully Associative Caches: –Every block can go in any slot •Use random or LRU replacement policy when cache full –Memory address breakdown (on request) •Tag field is unique identifier (which block is currently in slot) •Offset field indexes into block (by bytes) –Each cache slot holds block data, tag, valid bit, and citizen state bank friend ne

Data is moved from the main memory to the cache, so that it can be accessed faster. Modern chip designers put several caches on the same die as the processor; designers often allocate more die area to caches than the CPU itself.
