Consider two different implementations of the same instruction set architecture. There are four classes of instructions A,B,C D. P1 has a clock rate of 2.5Ghz and CPIs of 1 for A).2 (for B).3 (for C), and 3 for D). PI has a clock rate of 3 Ghz and CPIs of 2 (for A),2 (for B),2 (for C), and 2 (for D). Consider a program with 106 instructions were l0% is of type A. 20% is of type B, 35% is of type C and 35% is of type D. Answer the following (45-20) (a) What is the global CPI for each processor (b) What is the number of clock cycles required for each processor (c) Which processor is faster (d) Design a percentage of instructions that would make the other processor faster
