    摘要: In one embodiment, the present invention includes a directory to aid in maintaining control of a cache coherency protocol. The directory can be coupled to multiple caching agents via an interconnect, and be configured to store a entries associated with cache lines. The directory also includes logic to determine a time delay before the directory can send a concurrent snoop request. Other embodiments are described and claimed.

    摘要: According to one embodiment of the invention, a method comprises verifying that a cache block is not exclusively owned, and if not, transmitting a message identifying both the cache block and a caching agent requesting ownership of the cache block to a broadcast interconnect.
