What is snooping in computer architecture?
Snooping maintains the consistency of caches in a multiprocessor. The snooping unit uses a MESI-style cache coherency protocol that categorizes each cache line as either modified, exclusive, shared, or invalid. Each CPU’s snooping unit looks at writes from other processors.

What is snoopy bus protocol?
September 16, 2004. (n.) Also referred to as a bus-snooping protocol, a protocol for maintaining cache coherency in symmetric multiprocessing environments. In a snooping system, all caches on the bus monitor (or snoop) the bus to determine if they have a copy of the block of data that is requested on the bus.
How does a snoop filter work?
A snoop filter determines whether a snooper needs to check its cache tag or not. A snoop filter is a directory-based structure and monitors all coherent traffic in order to keep track of the coherency states of cache blocks. It means that the snoop filter knows the caches that have a copy of a cache block.

What is cache coherency in multicore architectures?
Cache coherency is a situation where multiple processor cores share the same memory hierarchy, but have their own L1 data and instruction caches. Incorrect execution could occur if two or more copies of a given cache block exist, in two processors’ caches, and one of these blocks is modified.
What is PCI Express no snoop?
