Question :
Suppose we have the following conditions:
1) Frequency of floating point (FP) operations is 24%;
2) Average CPI of FP operations is 5.0;
3) Average CPI of other instructions is 1.40;
4) Frequency of floating point squareroot (FPSQR) is 3%; and
5) CPI of FPSQR is 22.
Assume that the two design alternatives are to decrease the CPI of FPSQR to 2 or to decrease the average CPI of all FP operations to 2.4.
Compare the two design alternatives using Amdahl's law via performance.
