CACHE - SHOW YOUR WORK (Part A) Design a 512KB (note big B) direct-mapped data cache that uses a 32-bit address/data and 8 words per block. Calculate the following: (a) How many bits are used for the byte offset? (b) How many bits are used for the block offset? (c) How many bits are used for the set (index) field? (d) How many bits are used for the tag? (e) What is the physical size of the cache (show as bits/row * # of rows, x * 2v)?
