Abstract: A three-dimensional (3-D) look up table (LUT) can be accessed using an address decoder to identify a plurality of vertices in the 3-D LUT based on a number (m) of most significant bits (MSBs) of three coordinate values representative of a first color and a non-zero integer (p). The three coordinate values are determined by a source gamut. One or more memories store component values representative of a plurality of second colors determined by a destination gamut. The component values are stored at memory locations associated with the plurality of vertices. An interpolator maps the input color to an output color in the destination gamut based on the component values.

Abstract: A display processing device includes a display device interface and a processing unit. The processing is configured to transition at least a first component of the display processing system into a low-power state in response to an active region of a first video frame of a plurality of video frames having completed. A second component of the display processing device is configured to maintain a temporal count value corresponding to a current frame line of the plurality of video frames, and further to generate a first signal in response to the temporal count value corresponding to a first trigger value. The first signal causes the at least first component to transition out of the low-power state.
