Abstract
An apparatus and method for reducing power consumption in a portable terminal are provided. The apparatus includes a display unit for displaying at least one indicator that indicates status information measured by a slave processor, a master processor for controlling one of ON and OFF of the display unit and for providing image data to the display unit, and the slave processor for transmitting to the master processor indicator update information for updating the at least one indicator, wherein transmission to the master processor of the indicator update information is discontinued if the status of the display unit is OFF.
Claims20
An apparatus comprising:
- a display;
- a first processor operatively coupled with the display, the first processor configured to transmit a notification indicating that the display is in a first state to a second processor operatively coupled with the first processor;
- and
- the second processor configured to:
- transmit to the first processor information to update an indicator to be presented via the display;
- and
- cease to transmit the information to the first processor based at least in part on the notification.
A method comprising:
- obtaining, at an electronic device, information via a first processor operatively coupled with the electronic device so as to update an indicator to be presented via a display operatively coupled with the first processor;
- identifying, via the first processor, that the display is in a first state as set by a second processor operatively coupled with the display;
- and
- ceasing, via the first processor, to transmit the information to the second processor based at least in part on a determination that the display is in the first state.
A machine-readable storage device storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- obtaining, at an electronic device, information via a first processor operatively coupled with the electronic device so as to update an indicator to be presented via a display operatively coupled with the first processor;
- identifying, via the first processor, that the display is in a first state as set by a second processor operatively coupled with the display;
- and
- ceasing, via the first processor, to transmit the information to the second processor based at least in part on a determination that the display is in a first state.
