An n bit D/A decoder is formed using P-type and N-type transistor switches, instead of convention CMOS switches. Each P-type and N-type switch may be formed of fewer transistors than those used to form a CMOS switch, thereby reducing the overall transistor count. The decoder may be used to decode digital values to non-linear GAMMA corrected analog output voltages.

Reduced component digital to analog decoder and method

Systems and methods are provided for supporting an external display on a portable device. A system on a chip (SOC) of the portable device provides a first set of graphics data to a graphics controller. The embedded graphics controller renders the first set of graphics data for output using an LCD screen integrated with the portable device. The SOC renders a second set of graphics data and provides rendered graphics data to an external display interface. The external display interface formats the rendered graphics data for output on an external, remote display.

Portable device for providing dual display and method thereof

A system and methods are provided for processing graphics to be displayed in a portable device. A current mode of operation of the portable device is identified. In a normal mode of operation, image data associated with the portable device is rendered by a graphics system of the portable device and stored in memory external to the graphics system prior to display. When a screen refresh mode of operation is identified, image data rendered by the graphics system is compressed and stored in memory integrated internal to the graphics system. The present disclosure has the advantage of allowing the memory external to the graphics system to be disabled during the screen refresh mode of operation, reducing power consumed by the portable device.
