| Question 31 |
The performance of a pipelined processor suffers if
| the pipeline stages have different delays | |
| consecutive instructions are dependent on each other | |
| the pipeline stages share hardware resources | |
| All of the above |
Question 31 Explanation:
To speedup from pipelining equals the number of pipe stages are involve. Usually, however, the stages will not be perfectly balanced; besides, the pipelining itself involves some overhead.
If pipeline stages can’t have different delays, no dependency among consecutive instructions and sharing of hardware resources should not be there.
If pipeline stages can’t have different delays, no dependency among consecutive instructions and sharing of hardware resources should not be there.
