A) Briefly explain Amdahl's law and its applications to computer architecture. B) 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
