Abstract: A method includes: receiving a coherent request from a requester; looking up a state array of a snoop filter table corresponding to an index identified by the coherent request; determining state information corresponding to the coherent request; and determining to access one or more address tag arrays of the snoop filter table based on one or more of the state information, the requester, and a type of the coherent request.

Abstract: According to one general aspect, an apparatus may include a processor configured to issue a first request for a piece of data from a cache memory and a second request for the piece of data from a system memory. The apparatus may include the cache memory configured to temporarily store a subset of data. The apparatus may include a memory interconnect. The a memory interconnect may be configured to receive the second request for the piece of data from the system memory. The a memory interconnect may be configured to determine if the piece of memory is stored in the cache memory. The a memory interconnect may be configured to, if the piece of memory is determined to be stored in the cache memory, cancel the second request for the piece of data from the system memory.
