Problem #2 Consider two different implementations, Ml and M2, of the same instruction set architecture. There are four classes of instructions (A, B. C, D) in the instruction set. M1 has a clock rate of 2.5 GHz and M2 has a clock rate of 3 GHz. Given a program with dynamic instruction count (IC) of 10 instructions divided into four classes (the average number of cycles for each instruction class and their frequencies) as follows: Instruction Machine M1 Machine M2 Class Cycles/Instruction ClassCycles/Instruction Class Frequency 10% 50% 20% (i) (ii) Calculate the average CPI for each machine, M1 and M2. Calculate the program clock cycles and execution time for each machine, MI and M2
