Abstract
Apparatuses, systems and methods for performing efficient power management for a processing unit. A processing unit includes two partitions, each assigned to a respective power domain with operating parameters, and each with a respective direct memory access (DMA) engine. If a controller determines a task type of a received task indicates the task is to be processed by components of the second partition, then the controller assigns the task to the second partition and maintains the operational parameters of the first power domain for the components of the first partition or selects lower performance operational parameters of the first power domain. The processing unit accesses data stored in memory using a DMA engine and operational parameters of the second partition. Additionally, the second partition processes the task using the operational parameters of the second power domain.
