摘要: In an embodiment, a processor includes one or more cores, and a distributed caching home agent (including portions associated with each core). Each portion includes a cache controller to receive a read request for data and, responsive to the data not being present in a cache memory associated with the cache controller, to issue a memory request to a memory controller to request the data in parallel with communication of the memory request to a home agent, where the home agent is to receive the memory request from the cache controller and to reserve an entry for the memory request. Other embodiments are described and claimed.
