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. 6, 214, 175, 149, 214, 6 For each of these references, identify the address in hex, the tag, and the index given a direct-mapped cache with four-word blocks and a total size of 16 blocks. Also, list if each reference is a hit or a miss, assuming the cache is initially empty.
