What is the difference between cache coherence and consistency?
Cache coherence ensures that multiple caches in a system reflect the same data, while consistency refers to the overall state of data across the system.
Can you give an example of cache coherence in action?
Sure! In a multi-core processor, if one core updates a value in its cache, cache coherence protocols ensure that other cores see this updated value.
What are the types of consistency models?
There are several types, including strong consistency, eventual consistency, and causal consistency, each defining how updates are seen by different processes.
Why is cache coherence important in multi-core systems?
It's crucial because it prevents data inconsistency and ensures that all cores have a synchronized view of the data, which is vital for correct program execution.
