Consider two different machines, with two different instruction sets, both of which have a clock rate of 500 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 9 1 6 4 Arithmetic and logic Load and store Branch Others 3 4 6 2 Machine B Instruction Type Cycles per instruction Instruction Count (millions) 12 1 Arithmetic and logic Load and store Branch 9 3 3 4 6 Others 6 2 Q) Find the effective CPI, MIPS rate, the execution time and justify which of the two machines is faster (consider comparing the performance) and by how much times)
