Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions B, and in the instruction set. M1 has a dock rate of 114 MHz and M2 has a cock rate of 154 MHz. The average number of codes for each instruction class and their frequencies (for a typical program) are as follows: Instruction Class Machine M1 - Machine M2 - Frequency Cycles/Instruction Cycles/Instruction Class Class 1 2 60% B 3 30% 4 10% 2 4 Calculate the MIPS ratings for machine M2. (The answer is numerical value without unit)
