Abstract
The present disclosure relates generally to a system and method for monitoring a display output of a graphics processing unit (“GPU”), and more particularly, to monitoring safety critical symbols of a commercial off the shelf (“COTS”) GPU to ensure a high level of accuracy of the display output to be displayed to a user. The generated display output signal of the COTS GPU may be encoded with specific reference points within a generated image, and compared to a predicted image for the monitoring device having corresponding specific reference points. By having specific reference points in the encoded display output signal of the COTS GPU, the monitoring device may significantly reduce processing and throughput but focusing the comparison on only the specific encoded reference points and thereby confirming the accuracy of the COTS GPU.
