Abstract
Techniques for coherency management using distributed snoop requests are disclosed. A plurality of processor cores is accessed. The plurality of processor cores comprises a coherency domain. Two or more processor cores within the plurality of processor cores generate read operations for a shared memory structure coupled to the plurality of processor cores. Snoop requests are ordered in a two-dimensional matrix. The snoop requests are based on physical addresses for the shared memory structure. The two-dimensional matrix is extensible along each axis of the two-dimensional matrix. Snoop responses are mapped to a first-in first-out (FIFO) mapping queue. Each snoop response corresponds to a snoop request. Each processor core of the plurality of processor cores is coupled to at least one FIFO mapping queue. A memory access operation is completed, based on a comparison of the snoop requests and the snoop responses.
