2. Cache Replacement: a. Show how reference matrix method will function for a four-way set-associative map cache with the 6 Tag value sequence (12, 11, 12, 14, 12, 13). Assume all accesses are to the same "set" in the cache (i.e, all accesses have the same index value) 12 12 0 0 1 2 3 0 1 2 3 0 1 2 3 12 13 Ta b. Identify the hits (H) and misses (M) for the same cache structure for the 12 Tag sequence as follows: (12, 11, 12, 14, 12, 13, 15, 11, 12, 16, 15, 14).
