Patent ID: 11803224

Abstract:
The present disclosure provides a power management method, a multi-processing unit system, and a power management module thereof. The multi-processing unit system comprises a plurality of local power management units and a global power management unit, each of the local power management units corresponds to a processing unit of the multi-processing unit system. The power management method comprises: obtaining, using the global power management unit, a global power budget for the multi-processing unit system; allocating, using the global power management unit, local power budget for each of the local power management units according to the global power budget and power management parameters of the processing units; managing, using the local power management unit, local power resources of corresponding processing unit based on the allocated local power budget; reporting, using the local power management unit, the power management parameters of the processing unit to the global power management unit. The present disclosure improves the overall power efficiency for the multi-processing unit system.
