2. 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). P1 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 10% is of type A, 20% is of type B, 35% is of type C and 35% is of type D. Answer the following (4*5-20) (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
