A common transformation required in graphics engines is square root. Implementation of floating-point (FP) square root varies significantly in performance, especially among processors designed for graphics. Suppose FP square root (FPSQR) is responsible for 20% of the execution time of a critical graphics benchmark. One proposal is to enhance the FPSQR hardware and speed up this operation by a factor of 10. The other alternative is just to try to make all FP instructions in graphics processor run faster by a factor of 1.6; FP instructions are responsible for a total of 50% 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 fast square root. Compare speed up of these two design alternatives
