Question 5 [20 points]: Consider a 2-way set associative cache memory system in which: Main memory size = 128 bytes Cache memory size = 32 bytes Block size = 4 bytes Replacement algorithm: FIFO Write policy: write-back and write-allocate Note: Within a set, assume that main memory blocks are copied sequentially Given that the cache is initially empty and that the following decimal memory addresses are referenced: 34 [Read], 109 [Write], 58 [Read], 81 [Write], 114 [Read], 112 [Read], 121 [Read], 25 [Write], 32 [Write], 112 [Write] Map the memory blocks corresponding to the addresses to cache blocks and indicate whether hit or miss. Note: You must use the decimal approach in solving this question and you must show all computations and comments. You must state the type of each miss.
