  • Patent number: 11001143
    Abstract: Systems, methods, and devices of the various embodiments enable dynamic configuration of a number of display regions of interest (ROIs) associated with safety critical content presented on a display, such as a vehicle display. Various embodiments may enable verification of data integrity for ROIs on a display. Various embodiments may enable the selection of different sets of display ROIs from a plurality of independent sets of display ROIs each associated with its own set of stored integrity check values (ICVs). Various embodiments may enable stored ICVs to be used to verify the data integrity of ROIs on a display. Various embodiments may enable the set of display ROIs and the associated ICVs for each display ROI to be changed after a number of frames have been displayed.

  • Publication number: 20210064905
    Abstract: Certain aspects of the present disclosure generally relate to testing functionality of the display system. An example method generally includes selecting a first data integrity check value, associated with a region of interest (ROI) of an input frame, among a set of data integrity check values stored on a memory device, the data integrity check values are associated with an animation comprising a plurality of frames, and at least one of the frames of the animation corresponds to the input frame; processing, with a display processor, the input frame; calculating a second data integrity check value on the ROI of the input frame after the display processor processes the input frame; comparing, with a comparator, the data integrity check values; and generating, with the comparator, an interrupt if the comparison indicates that the values do not match.

  • Patent number: 10134139
    Abstract: Techniques of this disclosure may include processing one or more regions-of-interest (ROI) of an input image through a model of a display processor, calculating a first data integrity check value on the one or more ROI of the input image after processing through the model, processing the input image by the display processor, calculating a second data integrity check value on the one or more ROI by the display processor after the display processor processes the input image, comparing the first data integrity check value to the second data integrity check value, and generating an interrupt if the comparison indicates that the first data integrity check value and the second data integrity check value do not match.

  • Patent number: 10082860
    Abstract: This disclosure describes techniques for reducing power consumption of a display device. According to these techniques, a display device is configured to determine whether an image to be displayed by the display device has become static. In response to identifying such a static image, the display device may operate in a static image mode. According to the static image mode, the display device may read a current frame of image data, modify the current frame of image data to generate a modified frame of image data with a reduced size, and store the modified image data in memory. The display device may read the modified image data from memory to present the static image, which may reduce power consumption of the display device.

  • Patent number: 9955150
    Abstract: A display processor of a display system may receive an image that includes a test pattern. An input checksum may be associated with the test pattern. Hardware units of the display processor may process the image. The display system may generate an output checksum based at least in part on the test pattern after processing of the image. The display system may detect a fault in the hardware units of the display processor based on determining a difference between the input checksum and the output checksum.
