Solve part a using the given info

Consider two different machines A and B, with two different instruction sets. Machine A has a clock rate of 200 MHz while Machine B has a clock rate of 4 GHz. Assume a given program of 4 million instructions is being executed on both machines A and B. The program consists of four major types of instructions. The instruction mix and the CPI for each instruction type are given below: Machine A Instruction Type Logic and Arithmetic B Branch Load/Store with cache hit CPI 2 4 8 16 1 2 4 8 Instruction Mix (%) 60 18 12 10 Memory reference with cache miss Logic and Arithmetic Branch Load/Store with cache hit Memory reference with cache miss a. Determine the average CPI, MIPS rate, and execution time for each machine. 10 12 18 60
