[2] Consider two different implementations of the same instruction set architecture. There are four classes of instructions, A, B, C, and D. The clock rate and CPI of each implementation are given in the following table. Processor P1 P2 Clock Rate 2.5 GHz 3 GHz CPI Class A 1 2 CPI Class B 2 2 CPI Class C 3 2 (b) Which implementation is faster? (c) Find the clock cycles required in both cases. CPI Class D 3 2 (a) Given a program with 10° instructions divided into classes as follows: 10% class A, 20% class B, 50% class C, and 20% class D, what is the global CPI for each implementation?
