For this question only assume that the CPI for instruction C for Ml is 3.0+0.f and the CPIfor instruction C for M is 4.0+0.g Consider two different implementations M1 and M2 of the same instruction set. M1 has a clock rate of 2 GHz and M2 has a clock rate of 3 GHz. There are 3 classes of instructions with the following CPIs CPI for MI CPI for M2 Class 3 a) What are the peak performances in terms of MIPS for both machines? b) Show that if half the instructions executed in a certain program are from class A and the rest are divided equally among classes B and C, then M2 is faster than M1 (note that you may have to prove the opposite depending on your ID) Show that the second assumption in part b above is redundant. In other words, if half the instructions executed in a certain program are from class A, then M2 will always be faster than M1, regardless of the distribution of the remaining instructions among classes B and C. You need to prove this using an equation, for example if percentage of class B is x then percentage of class C is 0.5-x and solve for x. c)
