Suppose you have a machine that executes a program consisting of 50% floating point multiply, 20% floating point divide, and the remaining 30% are from other instructions. Management wants the machine to run 4 times faster. You can make the divide run at most 3 times faster and the multiply run at most 8 times faster. Can you meet management's goal by making only one improvement, and which one? Amdahl's Law states: Execution time after improvement (Execution time affected by improvement)/(Amount of Improvement) + Execution time unaffected =
