  • Patent number: 10659723
    Abstract: A data processing system includes a scaler 18 operable to scale a received input data array to provide a scaled output version of the input data array. When it is desired to produce a de-interlaced and scaled output version of an input data array 21, 22, the input data array 21, 22 is provided to the scaler 18, and the scaler 18 scales the input data array 21, 22 so as to simultaneously de-interlace and scale the input data array and to produce a de-interlaced and scaled output version of the input data array.

  • Patent number: 10649795
    Abstract: An apparatus for compositing an output surface (10) from a plurality of input surfaces (1, 2, 3, 4) includes processing circuitry and a composition processor. The processing circuitry is configured to determine whether two or more input surfaces of the plurality of input surfaces (1, 2, 3, 4) can be combined into a single secondary surface for provision to the composition processor. When it is determined that two or more input surfaces of the plurality of input surfaces (1, 2, 3, 4) can be combined into a single secondary surface for provision to the composition processor, the processing circuitry is configured to provide data representing the secondary surface to the composition processor, the data indicating the input surfaces that contribute to the secondary surface.

  • Patent number: 10592146
    Abstract: A method of operating a data processing system 4 is disclosed that comprises producing data in the form of blocks of data, where each block of data represents a particular region of a data array, processing the data using a processing operation in which one or more output data values are each determined using data values from plural different lines of the data array, storing the processed data in a memory 21 of the data processing system, and reading the data from the memory 21 in the form of lines.

  • Patent number: 10565966
    Abstract: In a display controller of a data processing system, when composing two or more input surfaces to generate a composited surface comprising the two or more input surfaces, data indicating a border between different input surfaces in the composited surface is associated with the composited surface. The data indicative of the border between two input surfaces in the composited surface is then used to control subsequent processing, such as compression and/or filtering, of the composited surface.

  • Patent number: 10496165
    Abstract: A device comprises a content-processing component operable to perform a content-processing operation. The device comprises a sensor operable to output data indicative of activity of an eyelid of a user of the device. The device comprises a processor configured to process the data output by the sensor, to cause the content-processing operation to be in an enabled state in response to the processing of the data output by the sensor indicating that the eyelid is open by more than an open-eyelid threshold, and to cause the content-processing operation to be in a disabled state in response to the processing of the data output by the sensor indicating that the eyelid is closed by more than a closed-eyelid threshold.

  • Patent number: 10276125
    Abstract: In a display controller, output surface data from a composition processing stage 22 is received by and stored in a local latency hiding buffer 40 of a memory write subsystem 31 before being written out to an external memory. The local buffer 40 of the memory write subsystem 31 signals when it is “full”, and in response thereto the inputting of output surface data to the local buffer 40 is stopped until the current line of the output surface has been finished, and then started again when the next line of the output surface begins. The writing of any data for the line of the output surface that was being written to the local buffer 40 that is already present in the local buffer 40 and not yet written to the external memory is also skipped, and it is recorded that the output surface line in question is not properly stored in the external memory.
