Abstract
A method comprising: sensing an ambient temperature at an electronic apparatus; and switching between a first processing mode of the electronic apparatus and a second processing mode of the electronic device, in response to an increase in the ambient temperature above a threshold.
Claims20
A method comprising:
- sensing an ambient temperature at an electronic apparatus;
- and
- switching between a first processing mode of said electronic apparatus and a second processing mode of said electronic apparatus, said method further comprising:
- a) estimating total power consumption of the first processing mode when processing a defined load at a sensed ambient temperature;
- b) estimating total power consumption of the second processing mode when processing the defined load at the sensed ambient temperature;
- and
- c) selecting the processing mode with the lowest estimated power consumption when processing the defined load at the sensed ambient temperature.

An apparatus comprising:
- an ambient temperature sensor for sensing ambient temperature;
- processing circuitry having a first processing mode and a second, different, processing mode;
- and a controller for selecting the processing mode of the processing circuitry in response to the sensed ambient temperature wherein the controller is operable to:
- a) estimate total power consumption of the first processing mode when processing a defined load at a sensed ambient temperature;
- b) estimate total power consumption of the second processing mode when processing the defined load at the sensed ambient temperature;
- and
- c) select the processing mode with the lowest estimated power consumption when processing the defined load at the sensed ambient temperature.

An apparatus as claimed in 50, wherein the controller is operable to select a processing mode when the defined load changes.
A method comprising:
- detecting a characteristic of processing circuitry;
- estimating total power consumption of a first processing mode of the processing circuitry, when processing a defined load, using the detected characteristic;
- estimating total power consumption of a second processing mode of the processing circuitry, when processing a defined load, using the detected characteristic ;
- and
- selecting the processing mode based on the estimated total power consumptions for the first processing mode and the second processing mode.
