a) Assume that a 20% change has been made to the single-processor MIPS command ADD, improving the CPI value from 4 to 3. Using Amdahl's Law, determine the impact of this change on total performance (Speedup=?)
b) If, without making any changes to the ADD command, an application A containing the command is executed in 20 minutes on a single-processor system and in 16 minutes on a two-processor system, determine its impact on total performance?
c) Which option provides a higher performance increase, and how much greater is the increase in performance compared to the other option?
