Consider the following statements and select the correct statements?

Answer: A. The performance of pipelined processor suffers if the pipeline stages have different delays.; C. The biased exponent in IEEE single precision format is 127.; D. The biased exponent in excess 64 is 2n−1 for n-bit exponent.

1. A.

   The performance of pipelined processor suffers if the pipeline stages have different delays.

2. B.

   Comparing the time T1​ taken for a single instruction on a pipelined CPU with time T2​ taken on a non-pipelined but identical CPU we can say that T1​≤T2​.

3. C.

   The biased exponent in IEEE single precision format is 127.

4. D.

   The biased exponent in excess 64 is 2n−1 for n-bit exponent.
