b) Consider a simple direct-mapped cache with 4 lines, each containing 4 bytes of data and a tag field of appropriate size given 8-bit addresses. Assume that the cache is initially empty and that memory is byte-addressable. For the following pattern of cache accesses: Memory hierarchy, direct-mapped cache draw up a table of form that summarises the contents of the cache after each access. For each access, in the Tag and Index columns write the values of the tag (in hex) and index (in decimal) corresponding to the access. Then, in the same row, indicate which line in the cache contains the data for the access by writing the tag (in hex) under the appropriate Line i column. Finally, in the last column, record an H or an M to indicate whether the access is a hit or a miss. [16ma
