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.
