Abstract
A graphics processing system for performing tile-based rendering of a scene that includes safety-critical elements. The graphics processing system includes a geometry engine configured to, in a geometry processing phase, identify protected tiles that include safety-critical elements; a fragment processing engine configured to, in a fragment processing phase, process each of the protected tiles first and second times so as to, respectively, generate first and second fragment-processed outputs; and a check unit configured to, for each of the protected tiles, compare the first and second fragment-processed outputs and raise a fault signal if the first and second fragment-processed outputs do not match.
