Abstract
A multi-processor unit includes a set of processing clusters. Each processing cluster is coupled to a data ring and a snoop ring. The unit also includes a snoop controller adapted to process memory requests from each processing cluster. The data ring enables clusters to exchange requested information. The snoop ring is coupled to the snoop controller—enabling the snoop controller to forward each cluster's memory requests to the other clusters in the form of snoop requests.
