Given: Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, and C) in the instruction set. Mi has a clock rate of 80 MHz and M2 has a clock rate of 100 MHz. The average number of cycles for each instruction class and their frequencies (for a typical program) are as follows: Machine M1 Machine M2 Instruction Class Frequency Cycles/ Instruction Class Cycles/ Instruction Class 1 2 60% B 2 3 30% c 4 10% Part 1: What is the average CPI for machine M2? a) 1.25 b) 1.5 c) 1.75 d) 2 e) 2.25 12.5 8) 2.75 b) 3 None of the answers listed Answer 1: (Note: Indicate ONLY the LETTER corresponding to your choice) Part 2: What is the average MIPS rating for machine M2? a) 40 b) 45 c) 50 d) 55 e) 60 f) 65 8) 70 h) 75 i) None of the answers listed Answer 2: (Note: Indicate ONLY the LETTER corresponding to your choice)
