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.
