Battery-powered device with reduced power consumption based on an application profile data

摘要

A device includes a processor that is operative to process a data stream such as executable code, encoded video or other suitable data stream, and has a plurality of processor portions. The device further includes a power management controller coupled to the processor portions that controls power consumption of the processor portions based on application profile data associated with the data stream. The application profile data may be included with executable code or provided separately and may directly indicate usage/nonusage of portions of the processor or the data stream may have inherent application profile data in the header that indirectly identifies usage of the processor portions.
