Coherence defines the behavior of reads and writes to a single address location. One type of data occurring simultaneously in different cache memory is called cache coherence, or in some systems, global memory. In a multiprocessor system, consider that more than one processor has cached a copy of the memory location X. The following conditions are necessary to achieve cache coherence: WebCache coherence is a technique used in computer architecture to ensure that multiple processors or cores have consistent data in their caches. In a multi-processor system, each processor has its own cache memory where it stores frequently accessed data.
