Consider two different implementations of the same instruction set archi- tectu CPI(class A, B, C and D). P1 with a clock rate of 2.5 GHz and CPIs of 1, 4, 2 and 2, and P2 with a clock rate of 3 GHz and CPIs of 2, 2, 2, and 2. re. The instructions can be divided into four classes according to their Given a program with a dynamic instruction count of 1.0E6 instructions divided into classes as follows: 10% class A, 30% class B, 50% class C, and 10% class D, which is faster: PI orP2? .What is the average CPI for each implementation? Find the clock cycles required in both cases esTnstructions can be,reduced by 20% by If the CPIof all these 4 typ some new theory, and if the research resource is limited and the engi- neers can only focus on improving the execution of one type instruction. Suppose you are the director of the research department, which type instruction will be chosen to be improved to maximumly increase the performance of the P1 based on the same instruction set? Why? Which instruction type will be chosen to increase the performance of the P2? Why
