Question 8 10 pts Consider two different implementations of the same instruction set architecture. The instructions can be divided into four classes according to their CPI (classes A, B, C, and D). P1 with a clock rate of 3.2 GHz and CPls of 1, 4, 3, and 2, and P2 with a clock rate of 2.9 GHz and CPls of 2, 2, 2, and 1. Given a program with a dynamic instruction count of 2.5E8 instructions divided into classes as follows: 15% class A, 15% class B, 40% class C, and 30% class D: a) What is the global CPI for each ISA implementation? b) Find the clock cycles required in both cases.
