Consider a series of word address references in memory:1,12, 16, 5, 20, 17, 19, 56, 9, 18, 2, 43, 4, 16, 19, 51. Assuming a direct-mapped(DM)cache with 4double-word blocks that are initially empty,show the contents of the cache after each reference specifying the byte address referenced, indicating whether it was a hit or a miss and specifying the block number and tag for each entry.Naturally all byte and word, etc. numbers begin with zero not one!
