Challenge Problems
Push your limits with advanced challenges
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.
💡 Hint: Think about the order in which instructions depend on one another and how forwarding can create an efficient flow.
Evaluate the impact on performance when implementing forwarding in a pipeline. Discuss the potential drawbacks of complexity on design considerations.
💡 Hint: Consider both the speed of execution and the resources needed to implement these techniques.
