2) Answer the following questions. Show your calculations. a) A 64Kbyte data, 8-word block, direct-mapped cache has blocks. b) A 64Kbyte data, 8-word, 2-way set associate cache has sets. c) Assume that we are given a direct-mapped cache of 16-blocks, where each block has 4 words. Memory byte address 1025 corresponds to block index d) Assume that we are given a 4-way set associative cache of 16-blocks, where each block has 4 words ( 1 word 4 bytes). Memory byte address 1025 corresponds to set index
