Question 1.
What is speculative execution?
Show hintHide hint
Think about what processors do before certain instructions are confirmed.
Question 2.
How does speculative execution impact instruction-level parallelism?
Show hintHide hint
Consider how it optimizes the use of the processor's pipeline.
3Question 3.
What is speculative execution?
- Executing confirmed instructions only
- Executing instructions based on predictions
- Avoiding execution until all paths are clear
Show hintHide hint
Focus on the future aspect of instruction execution.
4Question 4.
True or False: Speculative execution always leads to improved performance?
- True
- False
Show hintHide hint
Think about the consequences of wrong predictions.
Question 5.
Evaluate the impact of speculative execution on a multi-core processor design.
Show hintHide hint
Consider how each core can handle multiple paths of execution.
Question 6.
Explore how machine learning algorithms could enhance branch prediction accuracy in speculative execution.
Show hintHide hint
Think about the data-driven approach to enhance predictions.
