You are asked to evaluate performances of two desktop computers using a benchmark program that is a mixture of 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 | # of Clock Cycles # of instructions for Each Type in The Benchmark Programs # of Clock Cycles for Each Instruction Type # of Instructions for Each Type in The Benchmark Programs for Each Instruction Type 1 4 9 12 x 10 14 x 109 9 x 109 15 x 109 10 x 10 13 x 109 14 x 109 18 109 1 4 IV 4 a. Evaluate computer A and B based on the average CPI b. Which computer is faster on the total execution time? c. 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 V, which computer is better according to the execution time
