Challenge Problems
Push your limits with advanced challenges
Analyze a pipeline that executes an architecture with 5 stages, encountering a branch every third instruction. If the branch takes 4 cycles to resolve, how does this affect the overall rate of instruction completion?
💡 Hint: Calculate how many instructions effectively get processed in relation to branches.
Create a scenario in which branch decision delays have a minimal impact. What strategy could you implement in a superficial pipeline to achieve minimal delays?
💡 Hint: Consider how guessing the outcome might help.
