Abstract:
Systems, apparatuses, and methods for implementing dynamic control of a multi-region fabric are disclosed. A system includes at least one or more processing units, one or more memory devices, and a communication fabric coupled to the processing unit(s) and memory device(s). The system partitions the fabric into multiple regions based on different traffic types and/or periodicities of the clients connected to the regions. For example, the system partitions the fabric into a stutter region for predictable, periodic clients and a non-stutter region for unpredictable, non-periodic clients. The system power-gates the entirety of the fabric in response to detecting a low activity condition. After power-gating the entirety of the fabric, the system periodically wakes up one or more stutter regions while keeping the other non-stutter regions in power-gated mode. Each stutter region monitors stutter client(s) for activity and processes any requests before going back into power-gated mode.
