A common transformation required in graphics processors is squared root. Implementation of Floating Point (FP) square root varies significantly in performance. Suppose FP square root is responsible for 20% of the execution time of a critical graphics benchmark. One proposal is to enhance hardware and speed up this operation by factor 10. The other alternative is to make all FP instructions in the graphics processor run faster by a factor of 1.6; FP instructions are responsible for half of the execution time for the application. The design team believes that they can make all FP instructions run 1.6 times faster with the same effort as required for the first square root. What will the enhancement be for both cases?
