One machine uses a 2 GHz clock and executes a program with 4 classes of instructions, A, B, C, D. Their respective cycles/instruction are CPIA=3, CPIB=2, CPIC=4, and CPID=2. Another machine has a faster clock of 3.2 GHz, and a different architecture, such that the same classes of instructions have CPIA=2, CPIB=2, CPIC=3, and CPID=2. Both machines execute a program where the frequency of the four classes of instructions is 30% for Class A, 20% for Class B, 10% for Class C and 40% are instructions of Class D. a. How many instructions did each of the machines execute in 10 seconds (assume no overhead)? b. If a program has 10º instructions, which machines finishes first? c. Which machine is more performant? d. Compare the MIPS of the two machines.
