Consider a direct-mapped write-back cache with 16KB size and 32B line size. Assume that you would like to implement a least recently used (LRU) replacement policy in the cache. How many LRU bits would be required for the cache design? 0 1 2 3 4 Question 10 (3 points) Given the cache in the previous question, how many LRU bits would be required for the cache design if the line size is increased from 32B to 64B? 0 2 4 6 8
