Assume that the instrctions of a processor P can be divided into four classes according to their CPI(class A, B, C and D). The processor P has a clock rate of 2.5GHz and CPIs of 4, 2, 1 and 3 for class A, B, C and D respectively. Given a program with an instruction count of 1.0E6 instructions divided into classes as follow: 10% class A, 20% class B, 50% class C and 20% class D, compute : 1) the global (average) CPI 2) the clock cycles required 3) the execution time

Question

Assume that the instrctions of a processor P can be divided into four classes according to their CPI(class A, B, C and D). The processor P has a clock rate of 2.5GHz and CPIs of 4, 2, 1 and 3 for class A, B, C and D respectively.

Given a program with an instruction count of 1.0E6 instructions divided into classes as follow: 10% class A, 20% class B, 50% class C and 20% class D, compute :

1) the global (average) CPI

2) the clock cycles required

3) the execution time
