Question
Consider two different implementations of the same instruction set architecture (ISA).
The instructions can be divided into three classes according to their CPI (classes A, B, and C).
P1 with a clock rate of 2,5 GHz and CPIS of 1, 2, and 3, and
P2 with a clock rate of 3 GHz and CPIs of 2, 2, and 4.
Given a program with a dyñamic instruction count of 5 x 10 instructions divided
into classes as follows:
30% class A, 30% class B, and 40% class C.
A. What is the global CPI for cach implementation?
B. which is faster: P1 or P27 By how much?
C. Find the clock cycles required in both cases.
