Question 3 Four benchmark programs are executed on four (4) processors with the following results shown in Table Q3a. Table Q3a: Execution time (in second) for four processors Processor A Processor B Processor C 10 20 30 800 300 200 100 50 300 200 Benchmark Program 1 Program 2 Program 3 Program 4 200 300 Benchmark Program 1 Program 2 Program 3 Program 4 Processor D 10 700 300 300 Table Q3a shows the execution time in seconds, with number of instructions executed in each of the four programs is given in Table Q3b. Table Q3b: Number of instructions in the benchmark program Number of Instructions 100,000,000 800,000,000 120,000,000 600,000,000 Using inverse execution time and MIPS speed metrics, compare the ranking of the processors. Write your results in details and describe your findings
