Consider two different implementations of the same instruction set architecture on two different processors. The instructions can be divided into four classes according to their CPI (class A, B, C D). Processor P1 with a clock rate of 2GHz and CPIs of 1, 2, 3 and 4, and Processor P2 with a clock rate of 4GHz and CPIs of 3,3,3 and 5 . Given a program with a dynamic instruction count of 1.000.000 instructions divided into classes s follows: 20% class A, 10% class B, 30% class C, and 40% class D. Answer based on the solution of the following questions. (a) Find the clock cycles required in both processors. [7 points] (b) Find the total time required to execute this program in both processors. [7 points] (c) What is the global CPI of each processor? [7 points] (d) Which is faster for the given program? P1 or P2? [7 points] (e) What do you see as the biggest problem for the slower processor? [6 points]
