Question

What is the disadvantage of conditional jumps in pipelined CPUs?

a.

They are too fast and can cause data corruption.

b.

They are too slow and can cause performance issues.

c.

They are too unpredictable and can cause program crashes.

d.

They are too complex and can cause coding errors.

Posted under Reverse Engineering

Answer: (b).They are too slow and can cause performance issues. Explanation:The use of conditional jumps in pipelined CPUs can cause performance issues because the processor must guess or predict whether the jump will take place or not and based on that guess decide which instructions to add to the end of the pipeline. If it guesses wrong, the entire pipeline is emptied and must be refilled, which is a highly expensive operation.
