Interactive Quizzes

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

Question 1

What does cache coherence ensure?

  • That all processors see outdated data
  • The consistency of shared data among processors
  • That processors operate independently
  • No need for cache management

💡 Hint: Think about what happens when one processor updates shared data.

Question 2

True or False: Directory-based protocols do not require cache controllers to monitor the bus.

  • True
  • False

💡 Hint: Recall the difference between snooping and directory protocols.

Challenge Problems

Push your limits with challenges.

Question 1

You are developing a multi-threaded application that updates shared data frequently. Describe how you would implement cache coherence for this application and what challenges you might face.

💡 Hint: Consider the trade-offs between the two types of protocols.

Question 2

Analyze a multi-core processor architecture where snooping leads to deadlocks in several processors. What strategies could alleviate this situation?

💡 Hint: Think about how to streamline communication between caches.
