Abstract
A system for verifying the generation of a critical symbology includes a display processor configured to generate graphic commands from one or more system inputs. The display processor is further configured to determine the critical symbology. A graphics processing unit is coupled to the display processor. The graphics processing unit is configured to generate a plurality of pixels forming an image and is further configured to mark at least a portion of the plurality of pixels to produce marked pixels of the critical symbology. A graphics logic device is coupled to the graphics processing unit and includes an integrity monitoring function and a memory coupled to the integrity monitoring function. The integrity monitoring function is configured to detect the marked pixels and generate data regarding the critical symbology. The memory is configured to store the data regarding the critical symbology. A monitor warning function device is coupled to the graphics logic device and is configured to receive the data regarding the critical symbology and verify the generation of the critical symbology.
