Q1. You are asked to evaluate performances of two desktop computers on five different types of instructions. Computer A has a clock rate of 3.0GHz, while computer B has a clock rate of 2.7GHz. You are provided by the following measurements: Computer A Computer B Instruction Type Instruction Count 6 x 10 12 x 10 14 109 98 109 15 x 10 Instruction Count 8 x 10 10 x 109 13 109 14 109 18 x 109 CPI CPI IV I. II. 111. Evaluate computer A and B based on the average CPI. Which computer is faster on the total execution time? If you want to run some benchmarks that contain an instruction mix of 50% of type II, 30% of type IV, and 20% of type y, which computer is better according to the execution time
