摘要
A communication bypass mechanism accelerates cache-to-cache data transfers for communication traffic between caching agents that have separate last-level caches. A method includes bypassing a last-level cache of a first caching agent in response to a cache line having a modified state being evicted from a penultimate-level cache of the first caching agent and a communication attribute of a shadow tag entry associated with the cache line being set. The communication attribute indicates prior communication of the cache line with a second caching agent having a second last-level cache.
