Abstract
The field of the invention relates to the operational safety, security and reliability of Man/Machine Interface systems displaying information in the form of graphics or symbology. The monitoring principles according to the prior art are all based on monitoring graphical information coming from the display system and the verification that this information really corresponds to the input parameters. The heart of the invention is to monitor the correct operation of the graphics generation functions, independently of the data that they process. More precisely, the invention relates to a device for the graphical generation of symbologies intended for a display screen, the device having functions for the generation of symbology elements and means for monitoring its correct operation. The monitoring correct operation allows the use of certain of the functions for the generation of symbology elements to be prohibited and second allows micro-images dedicated to the monitoring of the functions to be generated and controlled.
