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. M1 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: Instruction Class Machine M1- Cycles/Instruction Class Machine M2 - Cycles/Instruction Frequency A B 1 2 4 Class 2 3 4 C Calculate the average CPI for machine M1. (The answer is numerical value without unit) Answer: 60% 30% 10%
