Bus sniffing

（重定向自Bus snooping）

Bus sniffing or bus snooping is a technique used in distributed shared memory systems and multiprocessors to achieve cache coherence. Although there is one main memory, there are several caches (one or more per processor), and unless preventative steps are taken, the same memory location may be loaded into two caches, and given two different values. To prevent this, every cache controller monitors the bus, listening for broadcasts which may cause it to invalidate its cache line.
