Abstract
Various methods for performing energy management via a sub-system are provided. One example method includes receiving a user input while a main processing system is in a power saving mode and buffering a representation of the user input. The example method further includes, in response to receiving the user input, triggering a wake up of a main processing system from the power saving mode, and causing transmission of the representation of the user input to the main processing system for processing. Similar and related example methods and example apparatuses are also provided.
Claims19
A method comprising:
- receiving a user input at a processing system comprising a main processing system and a sub-system while the main processing system is in a power saving mode;
- wherein the user input is received by the sub-system of the processing system;
- buffering a representation of the user input;
- and
- in response to receiving the user input:
- triggering, via a processor, a wake up of the main processing system from the power saving mode;
- causing transmission of the representation of the user input to the main processing system for processing;
- and
- causing the main processing system to return to the power saving mode in response to processing user input.
An apparatus comprising a processing system;
- wherein the processing system includes at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
- receiving a user input by a sub-system at a processing system comprising a main processing system and the sub-system while the processing system is in a power saving mode;
- buffering a representation of the user input in the sub-system;
- and
- in response to the sub-system receiving the user input:
- triggering a wake up of the main processing system by the sub-system from the power saving mode;
- causing transmission of the representation of the user input from the sub-system to the main processing system for processing;
- and
- causing the main processing system to return to the power saving mode in response to processing the user input.
A computer readable storage medium having computer program code stored thereon, the computer program code being configured to, when executed, cause an apparatus to perform:
- receiving a user input at a processing system comprising a main processing system and a sub-system while the main processing system is in a power saving mode;
- wherein the user input is received by the sub-system of the processing system;
- buffering a representation of the user input;
- and
- in response to receiving the user input:
- triggering a wake up of the main processing system from the power saving mode;
- causing transmission of the representation of the user input to the main processing system for processing;
- and
- causing the main processing system to return to the power saving mode in response to processing the user input.
