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That all processors see outdated data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.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
