For a cache with 16 blocks, 1) using direct-mapped placement, in which cache block (block number starts from 0) could memory block 57 can be found? 2) using 4-way associative placement, in which set (set number starts from 0) could memory block 57 can be found? Group of answer choices 10 ; 10 9 ; 1 10 ; 2 9 ; 9

1. Consider the following memory addresses: 3, 180, 43, 2, 191, 88, 190, 14, 181, 44, 186, 253 a. Assume the CPU has a cache consisting of 16 blocks, each one storing 1 word. Assuming the cache is initially empty, identify the index given to each address by a direct-mapped caching approach, and state whether each access is a cache hit or a miss. b. Repeat the previous exercise, but with a cache consisting of 8 blocks, each storing 2 words. c. Repeat the previous exercise, but this time with a 2 levels cache, where L1 consists of 2 blocks with 4 words each, and L2 consists 4 blocks with 4 words each. d. Suppose you have cache with a total of 8 words of storage. Which cache design would yield better performance (in terms of hits and misses) with these accesses: 1 word blocks, 2 word blocks, or 4 word blocks?
