NEED SOLUTION TO PROBLEM Number 2. PLEASE explain all steps to approach the solution carefully

Problem 1- Assume a CPU has the following instruction mix and CPI: Instruction type | % of instructions Arithmetic Load/Store Conditional Multiply/Division10 50 25 15 CPI 2 12 The clock rate is 2GHz. You have received 2 competing proposals to improve performance: I. To have a special multiply/division unit that performs multiplication and division in 2 cy 2. To increase the clock to 3GHz, that will increase load/store by one cycle and the multi- Which of these 2 proposals is better (or none of them, the current one is better)? Justify your cles. You need to reduce the clock rate to 1.7GHz. ply and division by 2 cycles
