Consider 2 machines, A and B on which the following measurements are made for a certain program P. A: Execution time of P: 5 sec Instructions Executed: 5.4 x 10⁸ CPI: 1.8 B: Execution time of P: 6.4 sec Instructions executed: 115 x 10⁶ CPI: 2.0 a. Find the execution rate (in Millions of Instructions per Second (MIPS)) for each machine. b. Find the clock cycle for each machine. c. Using the books definition of performance measure, which machine is faster and by how much.
