Basic Cache Coherence

This lecture covers the fundamental concepts of cache coherence in computer systems, focusing on the basic principles of cache organization and management. Starting with an overview of the memory hierarchy and cache structure, the instructor explains the ABC's of caching, including block placement, identification, replacement, and write strategies. The lecture delves into different cache coherence protocols, such as MSI and MOESI, discussing their design choices and implications. It also explores the challenges of implementing cache coherence in multi-level cache hierarchies and the importance of maintaining cache inclusion. The presentation concludes with a summary of the key concepts and protocols discussed.
