4. Performance measurement The machine M is a 1 GHz implementation of the ARM instruction set. A benchmark program run on machine M has the following instruction breakdown Instruction Type Frequency CPI Arithmetic Write Read 50% 10% 25% |2 1. If the average CPI of M for the benchmark program is 5, what is the CPI for write instruction? 2. If the total execution time of the benchmark program is 10 ms, what is the total number of instructions in the program? 3. A design team wishes to improve the performance of machine M on the benchmark program. They are able to reduce the excution time of write type instruction by 50%. and the performance for the other types of instruction remains unchanged. What is the improvement on the overall performance of machine M in terms of excution time
