Solve (e) number only

Question 5 (Computer Performance): 5x2 = 10 marks You are on the design team for a new processor. The clock of the processor runs at 200 MHz. The following table gives instruction frequencies for Benchmark program, as well as how many cycles the instructions take, for the different classes of instructions. For this problem, we assume that (unlike many of today's computers) the processor only executes one instruction at a time. 6 Instruction Type Frequency CPI Loads & Stores 30% Arithmetic Instructions 50% 4 All Others 20% 3 a) Calculate the CPI for Benchmark program. b) What is the MIPS rating of the processor speed? c) The hardware expert says that if you double the number of registers, the cycle time must be increased by 20%. What would the new clock speed be in MHz)? d) The compiler expert says that if you double the number of registers, then the compiler will generate code that requires only half the number of Loads & Stores. What would the new CPI be on the benchmark? e) How many CPU seconds will the benchmark take if we double the number of registers (taking into account both changes described above)
