Abstract
A shared cache is point-to-point connected to a plurality of point-to-point connected processing nodes, wherein the processing nodes may be integrated circuits or multiprocessing systems. In response to a local cache miss, a requesting processing node issues a broadcast for requested data which is observed by the shared cache. If the shared cache has a copy of the requested data, the shared cache forwards the copy of the requested data to the requesting processing node.
