2. Consider two different machines, with two different instruction sets, both of which have a clock rate of 150 MHz. The following measurements are recorded on the two machines (Machine A and Machine B) running a given set of benchmark programs: Machine A Instruction Type Instruction Count (millions) Cycles per instruction 3 Arithmetic and logic Load and store Branch Others 3 2 2 2 Machine B Instruction Type Instruction Count (millions) Cycles per instruction 11 1 Arithmetic and logic Load and store Branch Others 2 4 2 2 2 Determine the effective i) CPI, ii) MIPS rate, and iii) execution time for each machine
