    摘要: A system and method of optimized user coherence for a cache block with sparse dirty lines is disclosed wherein valid and dirty bits of each set are logically AND'ed together and the result for multiple sets are logically OR'ed together resulting in an indication whether a particular block has any dirty lines. If the result indicates that a block does not have dirty lines, then that entire block can be skipped from being written back without affecting coherency.
