Abstract
Circuits, methods, and systems that reduce or eliminate the number of data transfers between a system memory and a graphics processor under certain conditions. After inactivity by a user of an electronic device is detected, the color fidelity of pixels being displayed is reduced. Color fidelity can be reduced by compressing pixel values, and the compression may be non-lossless, for example, pixel data bits may be truncated. The degree of compression can be progressively increased for longer durations of inactivity, and this progression may be limited by a threshold. Inactivity may be detected by a lack of input from devices such as a keyboard, pen, mouse, or other input device. Once activity is resumed, uncompressed pixel data, or pixel data that is compressed in a lossless manner, is displayed.
