Caches are important to providing a high-performance memory hierarchy to processors. Below is a list of 32-bit memory address references, given as word addresses. 4, 180, 43, 2, 191, 88, 190, 14, 181, 44, 186, 253 a. For each of these references, identify the binary address, the tag, and the index given a direct-mapped cache with 16 one-word blocks. Also list if each reference is a hit or a miss, assuming the cache is initially empty. b. For each of these references, identify the binary address, the tag, and the index given a direct-mapped cache with two-word blocks and a total size of 8 blocks. Also list if each reference is a hit or a miss, assuming the cache is initially empty.

a. For each of these references, identify the binary address, the tag, and the index
given a direct-mapped cache with 16 one-word blocks. Also list if each reference is a hit
or a miss, assuming the cache is initially empty.
b. For each of these references, identify the binary address, the tag, and the index
given a direct-mapped cache with two-word blocks and a total size of 8 blocks. Also list
if each reference is a hit or a miss, assuming the cache is initially empty.
