    Abstract: In addition to rendering a first frame representing a first forward view of a scene, a graphics processing system renders one or more further versions of the first frame, each representing a further view of the scene based on a different point in time and/or view orientation. The first frame and/or one or more of the one or more further versions may then be subjected to “timewarp” and/or “spacewarp” processing to generate an output “timewarped” and/or “spacewarped” image 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. The method comprises the display controller providing to the display data for an output surface to be displayed, storing the data in a memory of the display, and the display reading the data from the memory and displaying the output surface. The method further comprises the display controller indicating to the display a particular memory address of the memory, and the display using the indication to control the reading of data from the memory. The display controller may provide to the display image data for one or more sub-regions of the output surface that were not present in a previous version of the output surface.

    Abstract: A data processing system comprises encoding circuitry operable to encode arrays of data elements, decoding circuitry operable to decode encoded versions of arrays of data elements, and consumer circuitry operable to use arrays of data elements. Data indicative of a resolution that is to be used by the consumer circuitry for at least one region of the array of data elements is provided to the encoding circuitry, and the encoding circuitry uses the data indicative of the resolution that is to be used by the consumer circuitry to control the generation of the representation for representing at least one block that the array of data elements is divided into.

    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.
