Abstract
This invention optimizes non-shared accesses and avoids dependencies across coherent endpoints to ensure bandwidth across the system even when sharing. The coherence controller is distributed across all coherent endpoints. The coherence controller for each memory endpoint keeps a state around for each coherent access to ensure the proper ordering of events. The coherence controller of this invention uses First-In-First-Out allocation to ensure full utilization of the resources before stalling and simplicity of implementation. The coherence controller provides Snoop Command/Response ID Allocation per memory endpoint.
