8. Assume that the frequency of Floating Point (FP) operations is 25% for a computer, andthe average CPI (Clock Cycles Per Instruction) of FP operations is 4. The average CPI ofother instructions is 1.5. By performing some enhancement on the hardware, we canreduce the average CPI of all FP operations to 2. All other factors are not changed afterenhancement. Which of the followings are true?
(A)The speedup for the FP operations is 2
(B) The total speedup can be computed by Amdahl's Law using the following equation:

(C)The total speedup is 1.307
(D)The CPI after enhancement is 1.859
(E) The CPI before enhancement is 2.125
