Title
(EN) PROCESS FOR MONITORING ELECTRONIC COMPUTING ELEMENTS, PARTICULARLY MICROPROCESSORS
(FR) PROCEDE DE SURVEILLANCE D'ELEMENTS DE CALCUL ELECTRONIQUES, EN PARTICULIER DES MICROPROCESSEURS
Abstract
(EN)
Process intended, in the case of microprocessors (1) provided with a monitoring device (2) with signal generation steps for reset signals, to enable a recognition to know wether a reset signal comes from the monitoring device (2) or from a power-on-reset circuit (5). A comparison is then effected between a comparison sample stored in a known volatile storage area (6) and a characteristical sample or the resetting operation by the monitoring device (2) in the volatile storage area (7).
(FR)
Procédé servant, dans le cas de microprocesseurs (1) dotés d'un dispositif de surveillance (2) avec seuils de production de signaux pour des signaux de remise à l'état initial, à permettre une reconnaissance pour savoir si un signal de remise à l'état initial provient du dispositif de surveillance (2) ou d'un circuit de remise sous tension (5). Une comparaison est alors effectuée entre un échantillon de comparaison déposé dans une zone de mémoire rémanente (6) et un échantillon typique pour la remise à l'état initial par le dispositif de surveillance (2) dans une zone de mémoire non-rémanente (7).
