Design of associative cache
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. Both these … Web2 3 Set associative caches are a general idea By now you have noticed the 1-way set associative cache is the same as a direct-mapped cache Similarly, if a cache has 2k blocks, a 2k-way set associative cache would be the same as a fully-
