2. (3 points) The following table shows the cycles per instruction (CPI) and instruction counts for four different instruction types (namely, A, B, C, D) for two different CPUs (CPU1 and CPU2). The clock frequencies for CPU1 and CPU2 are 2.4 GHz and 2.8 GHz, respectively. (a) Find the number of executed cycles for CPU1 and CPU2 (b) Find the performance ratio of CPU1 and CPU2. CPU1 CPI Instrs. 30 50 60 30 CPU2 CPI Instrs. 10 70 70 20
