In a k way set associative cache

WebIn a k-way set associative cache, the cache is divided into v sets, each of which consists of k lines. The lines of a set placed in sequence one after another. The lines in set s are sequenced before the lines in set (s+1). The main memory blocks are numbered 0 on wards. WebThe k-way set associative mapping refers to a combination of the direct mapping as well as the fully associative mapping. It makes use of the fully associative mapping that exists within each set. Therefore, the k-way set …
