An '''Inter-Processor Interrupt''' ('''IPI''') is a special type of [[interrupt]] by which one processor may interrupt another processor in a [[multiprocessor]] system. IPCsIPIs are typically used to implement a [[cache coherency]] [[synchronization]] point.

In [[x86]] base systems, an IPI synchronizes the cache and [[Memory Management Unit]] (MMU) between processors.
