Design of associative cache

Webcache is a small fully-associative cache containing on the order of two to five cache lines of data. When a miss occurs, data is returned not only to the direct-mapped cache, but also to the miss ... However, the line size of the second level cache in the baseline design is 8 to 16 times larger than the first-level cache line sizes, so this ... Weborganizations: direct mapped cache, fully associative cache and set associative cache. Each organization can be better for a specific workload, that is, a specific memory trace behavior. However, it is difficult to design a cache that has a high performance for all different workloads of a general purpose processor. Thus, the designers choose cache
