(6 pts) Consider two different implementations of the same instruction set architecture. The instructions can be divided into four classes according to their CPI (class A, B, C, and D). P1 with a clock rate of 3GHz and CPIs of 3, 2, 3, and 1, and P2 with a clock rate of 2.4GHz and CPIs of 2,2,2, and 2 . Given a program with a dynamic instruction count of 1.0106 instructions divided into classes as follows: 10% class A, 20% class B, 50% class C, and 20% class D. a. What is the average CPI for each implementation? b. Find the clock cycles required in both cases. c. Which is faster: P1 or P2
