Please answer all the parts thank you.

Chol.1. Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, and C) in the instruction set. Mi has a clock rate of 100 MHz and M2 has a clock rate of 140 MHz. The average number of eycles for each instruction class and their frequencies (for a typical program) are as follows: Frequency Instruction Class Machine M1 Cycles/Instruction Class 1 Machine M2 - Cycles/Instruction Class 2 A 55% 3046 3 B 2 4 (a) Calculate the average CPI for each machine, MI, and M2 (show your work). (b) Calculate the average MIPS ratings for each machine, M1 and M2 (show your work). (see textbook p.51) (c) Which machine has a smaller MIPS rating? Which individual instruction class CPI do you need to change, and by how much, to have this machine has the same or better performance as the machine with the higher MIPS rating (you can only change the CPI for one of the instruction classes on the slower machine)?
