    摘要: Methods and apparatus relating to allocation and/or write policy for a glueless area-efficient directory cache for hotly contested cache lines are described. In one embodiment, a directory cache stores data corresponding to a caching status of a cache line. The caching status of the cache line is stored for each of a plurality of caching agents in the system. An write-on-allocate policy is used for the directory cache by using a special state (e.g., snoop-all state) that indicates one or more snoops are to be broadcasted to all agents in the system. Other embodiments are also disclosed.

    摘要: Methods and apparatus relating to Opportunistic Snoop Broadcast (OSB) in directory enabled home snoopy systems are described. In one embodiment, a plurality of snoops are broadcast to a plurality of caching agents in response to a request for data and based on a comparison of a bandwidth consumption of the link and a threshold value. Other embodiments are also disclosed.
