Coherence protocols apply cache coherence in multiprocessor systems. The intention is that two clients must never see different values for the same shared data. The protocol must implement the basic requirements for coherence. It can be tailor-made for the target system or application. Protocols can also be classified as snoopy or directory-based. Typically, early systems used dir… Web•A main memory block can load into any line of cache •Memory address is interpreted as a combination of a tag field and a word field •Tag uniquely identifies block of memory •Number of lines in cache does not correlate to how address bits are used.
