Suppose that a FSQRT function is responsible for 40% of the execution time of some application and all floating-point FP instructions (ALLFP) are responsible for 55%. To improve the performance of this application, the developers asked you to help them select the best of the following two choices: (Show all your calculations).

• First choice: to speed up the function FSQRT by a factor of 10
• Second choice: execute ALLFP instructions 2x faster.
