Consider two different implementations of the same instruction set architecture. The instructions can be divided into four lasses according to their CPI (class A, B, C, and D). P1 has a clock rate of 2.5 GHz and CPIs of 1 (class A), 2 (Class B), 3 (class C), and 3 (class D).

Given a program with a dynamic instruction of 1.0E6 instructions divided into classes as follows: 20% class A, 10% class B, 50% class C, 20% class D.

a) What is the global CPI?

b) Find the clock cycles required to run the program on P1.
