Can you explain what the MESI protocol is?
The MESI protocol is a cache coherence protocol used in multiprocessor systems to maintain consistency between caches.
What does MESI stand for?
MESI stands for Modified, Exclusive, Shared, and Invalid, which are the four states a cache line can be in.
How does the MESI protocol ensure data consistency?
It ensures data consistency by managing the states of cache lines and coordinating between different processors to avoid stale data.
Can you give an example of how MESI works in practice?
Sure! If one processor modifies a cache line, the MESI protocol will mark that line as Modified and notify other processors to invalidate their copies.
