Consider a cache memory with 8 cache blocks (0-7). If the memory block requests are in the following order- 3, 5, 2, 8, 0, 6, 3, 9, 16, 20, 17, 25, 18, 30, 24, 2, 63, 5, 82, 17, 24 What is the hit ratio for the above block requests for the following replacement algorithms. a) LRU b) 2-way set associative mapping using LRU
