Question 1.
What is a pipeline stall?
Show hintHide hint
Think about what happens when data is not ready for processing.
Question 2.
What does forwarding achieve in a pipeline?
Show hintHide hint
Consider how data might flow in a pipeline.
3Question 3.
What is a pipeline stall?
- A delay due to a hardware failure
- A delay due to data dependency
- A delay due to an unknown error
Show hintHide hint
Consider situations where one instruction depends on the result of another.
4Question 4.
True or False: Forwarding allows data to be passed directly between pipeline stages without going through registers.
- True
- False
Show hintHide hint
Think about how data flows in a pipeline.
Question 5.
Design a simplified pipeline with four stages and illustrate how stalls could occur when executing the sequence of instructions, including at least one instance of forwarding.
Show hintHide hint
Think about the order in which instructions depend on one another and how forwarding can create an efficient flow.
Question 6.
Evaluate the impact on performance when implementing forwarding in a pipeline. Discuss the potential drawbacks of complexity on design considerations.
Show hintHide hint
Consider both the speed of execution and the resources needed to implement these techniques.
