Consider two different implementations of the same instruction set architecture. The instructions can be divided into four classes A, B, C, and D according to their CPI. the clock rate and CPI of each implementation are given in the following table. Clock Rate CPI class A CPI class B CPI class C CPI class D a. P1 2.5 GHz 1 3 P2 3 GHz 12 1) 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? 2) What is the global CPI for each implementation? 2
