Abstract
A cache architecture to increase communication throughput and reduce stalls due to coherence protocol dependencies. More particularly, embodiments of the invention include multiple cache agents that each communication with the same protocol agent. In one embodiment, a pre-coherence channel couples the cache agents to the protocol agent to enable the protocol agent to receive events corresponding to cache operations from the cache agents to maintain ordering with respect to the cache operation events.
