Abstract
A high integrity, high availability avionics display architecture for an avionics display system. The architecture includes a plurality of display processing computers (DPC) and a plurality of display integrity feedback interfaces. Each DPC includes at least two independent processing channels. Each independent processing channel includes at least two independent lanes. Each independent lane includes an I/O section and a processor section. Furthermore, each independent processing channel comprises an operative graphics section. At least one of the independent lanes provides a critical display function that provides commands to the graphics section to drive a display signal to displays of the avionics system. A number of display integrity feedback interfaces from the displays of the avionics display system provide integrity by allowing the integrity monitor functions to detect faults within the display signals and/or originating from the displays.
