Webmatches a tag within the set specified by set index, then there is a cache hit. Otherwise, the appropriate block is loaded from memory. The number of bits in the tag depend on the number of bits in the set index and block offset. Essentially, the tag bits are the leftover bits after the set index block offset are calculated. WebIf the cache is direct-mapped, then of the next 29 bits, 11 bits are an index into the cache, and the remaining 18 bits are address tag. If the cache is fully associative, then all 29 bits are tag. And everything in between: four-way set associative means there are 11 - 2 = 9 set index bits, and the tag is 18 + 2 = 20 bits.
