. Consider two different implementations, M1 and M2. The same instruction set is adopted, containing instruction type A, B and C with different number of cycles to complete. The instruction mixes are different on M1 and M2 though the total numbers of instructions run for a program are the same. M1 M2 Instr. CPI usage CPI usage A 2 35% 2 25% B 3 43% 5 25% C 5 22% 2 50% (1) If the clock cycle time on M1 is 1.1 times of that on M2, how many times faster is M2 than M1
