Can you explain why cache coherency is important in computer systems?
Cache coherency ensures that multiple caches in a system reflect the same data, preventing inconsistencies.
What happens if cache coherency is not maintained?
Without cache coherency, different processors may work with outdated or incorrect data, leading to errors.
How do modern processors handle cache coherency?
Modern processors use protocols like MESI (Modified, Exclusive, Shared, Invalid) to maintain cache coherency.
Are there performance impacts due to cache coherency?
Yes, maintaining cache coherency can introduce latency, but it's essential for data integrity.
