Here is a series of address references given as words addresses: 3, 7, 1, 10, 11, 13, 11, 64, 1, 10. a. Assuming a direct-mapped cache with 8 one-word blocks that is initially empty, label each reference in the list as a hit or a miss and show the contents of the cache (including previous, over- written values). You do not need to show the tag field. When done, include the hit ratio. If you have entry in cache then valid bit is 1 else zero.
