Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Explain how the MESI protocol prevents data inconsistency in a multi-core system. Provide an example of a situation where it would be critical.

💡 Hint: Consider shared resources in scenarios requiring simultaneous data updates.

Challenge 2 Hard

Discuss the trade-offs of using snooping protocols versus directory-based protocols for cache coherence in a large-scale multi-core processor.

💡 Hint: Think about how communication scales with more processors.
