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.
Given a program with 106 instructions divided into classes as follows: 10% class A, 20% class B, 50% class C, and 20% class D, which implementation is faster?
a. b. P1 P2 P1 P2 Clock Rate 2.5 GHz 3 GHz 2.5 GHz 3 GHz CPI Class A CPI Class B CPI Class C CPI Class D 1 2 2 1 2 2 1.5 2 3 2 2 1 3 2 1 1
