1. The following measurements have been made on machine Ml and M2 Program Time on Mi Time on M2 i 15 seconds 8 seconds 4 seconds 6 seconds Program Instruction executed on Mi Instructions executed on M2 300x106 190x106 1 a. Which machine is faster for each program and by how much? b. Find the instruction execution rate instruction per second) for each machine when running program 1. c. Find the clock cycles per instruction (CPI) for program 1 on both machines if the clock rate of machine M1 and M2 are 200MHz and 300MHz, respectively
