MESIprotokollen
MESI is a cache coherence protocol used in multiprocessor systems. It stands for Modified, Exclusive, Shared, and Invalid, which are the four states a cache line can be in. These states ensure that all processors have a consistent view of memory, preventing data corruption.
The Modified state indicates that the cache line has been modified by the current processor and is
When a processor accesses data, its cache controller checks the state of the corresponding cache line. If
MESI relies on bus snooping, where cache controllers monitor the system bus for memory transactions initiated
