Abstract

An apparatus and method for processing efficient multicast operation. For example, one embodiment of a processor comprises: a plurality of cores to execute instructions; a shared circuitry region to be shared by the plurality of cores; first cache management circuitry associated with the shared circuitry region to receive delayed prefetch messages from the cores, each delayed prefetch message comprising an address or portion thereof usable to identify a cache line; and a delayed prefetch manager comprising a plurality of entries, each entry associated with at least one of the delayed prefetch messages, the delayed prefetch manager to update one or more of the entries or generate a new entry in accordance with receipt of each new delayed prefetch message, wherein upon receiving a notification that a first cache line is being modified by a first core, the delayed prefetch manager is to transmit delayed prefetch response messages to one or more cores identified in a first entry associated with the first cache line.
