Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What is the formula for calculating speedup?

  • Speedup = Execution Time of Pipelined System / Execution Time of Non-Pipelined System
  • Speedup = Execution Time of Non-Pipelined System / Execution Time of Pipelined System
  • Speedup = Execution Time of Pipelined System + Execution Time of Non-Pipelined System

💡 Hint: Think about what speedup compares.

Question 2

True or False: The ideal speedup factor for a perfectly balanced N-stage pipeline is N.

  • True
  • False

💡 Hint: Consider what happens as instructions flow through a well-structured pipeline.

Challenge Problems

Push your limits with challenges.

Question 1

A non-pipelined processor takes 12 seconds to complete a task. A pipelined processor, with a 4-stage pipeline, completes the same task in 3 seconds. Calculate the speedup factor and evaluate the efficiency if the maximum theoretical speedup is 4.

💡 Hint: Think about the formulas we've covered for speedup and efficiency.

Question 2

Describe a scenario where hazards in the pipeline could drastically affect throughput. What strategies could mitigate this effect?

💡 Hint: Reflect on the types of hazards we've discussed and ways to navigate them effectively.
