More Information
Summary:This disclosure describes systems, methods, and apparatus for reducing power consumption of an application processor in a user equipment. State information of applications that indicate an expected load requirement that the applications will likely place on the application processor, can be used to control power management features of the application processor. For instance, an operating frequency of the application processor, or online cores of the application processor, can be reduced. The number of online cores (those that are not idled) can also be changed to tailor performance and power consumption to the load requirement. Other power management techniques such as adjusting core operational voltage can also be implemented.
