Abstract: A display controller for a data processing system comprises two sets of display processing units, each set of display processing units comprising an input unit operable to read at least one input surface, a processing unit operable to process one or more input surfaces to generate an output surface, and an output unit operable to provide an output surface for display to a display. The display controller also includes internal data path via which pixel data of a surface may be passed between the sets of display processing units, and a control unit that can selectively activate one or both of the sets of display processing units to process one or more input surfaces to generate one or more output surfaces for display.

Abstract: A method of operating a data processing system is disclosed for a data processing system that comprises a display and a display controller operable to provide to the display data in respect of output surfaces to be displayed. The method comprises, when an output surface is to be displayed, the display controller providing to the display data in respect of the output surface in the form of image data and image modification data, and the display using the image data and the image modification data when producing an output surface for display.
