Cache Controller for 4-way Set-Associative Cache Memory

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 … WebA set-associative cache uses multiple frames for each cache line, typically two or four frames per line. A fully associative cache can place any block in any frame.
