Abstract: This graphics processor comprises: a generating module configured to generate at least one set of pixel(s) to be displayed; a display module connected to the generating module, the display module being configured to display each set of pixel(s) on a screen; and a monitoring unit integrated into the generating module, the monitoring unit being configured to determine a list of graphic context information item(s) for at least one pixel and to deliver said list to an external electronic supervision device, able to be connected to the graphics processor.

Abstract: The object of the invention is a method for securing a vehicle comprising a critical system including a display, the method comprising the following steps: acquisition of at least one video stream to be shown on the display; calculation of a brightness level of the or each video stream; if the brightness level of the video stream(s) meets a predefined criterion, then the video stream is displayed on the display; otherwise, display of the video stream is inhibited.

Abstract: The invention relates to a method and system for validating the graphical generation of symbols to display, comprising a graphical generation of symbols to display to form a video stream comprising a plurality of rasters, comprising a pixel generation, with the attribution of at least one associated symbol attribute for each pixel contributing to one of said symbols. The method comprises, for at least one raster of said video stream: obtaining at least one reference symbol attribute associated with at least one symbol to be monitored; identifying pixels having the reference symbol attribute(s), during a scan of the pixels of said raster in a predetermined course direction, these pixels contributing to said at least one symbol to be monitored, and calculating associated characteristic information; validating the display of the symbol(s) to be monitored based on the calculated characteristic information and of source information associated with said symbols to display.

Abstract: This method for generating graphic surfaces to be displayed on a screen is implemented by a graphics processor and comprises: generating a first graphic surface to be displayed on the screen; switching between generating the first graphic surface and generating a second graphic surface; generating the second graphic surface to be displayed on the screen; the switching including saving a graphic execution context of the first graphic surface; and if the generation of the second graphic surface had been interrupted during a preceding switch with the generation of another graphic surface, restoring a graphic execution context of the second graphic surface, the restored context having been saved during said preceding switch.
