WebQuestion: Consider a memory system with a 4-bit address space and a 2way Set associative cache, that has four sets and 2 bytes per block. Given this binary bit pattern, 0100 , what is the TAG? Question 20 1 pts Consider a memory system with a 4-bit address space and a 2way Set associative cache, that has four sets and 2 bytes per block. WebThe second to last 0 is a capacity miss because even if the cache were fully associative with LRU cache, it would still cause a miss because 4,1,2,3 are accessed before last 0. However the last 0 is a conflict miss because in a fully associative cache the last 4 would have replace 1 in the cache instead of 0.
