Abstract

L’invention concerne une passerelle (1) de communication de trames de données pour véhicule automobile, ladite passerelle étant destinée à être connectée à une pluralité d’unités de contrôle électronique afin d’échanger des trames de données, ladite passerelle (1) comprenant : - autant de modules de gestion (13) que d’unités de contrôle électronique, - une mémoire (12) dans laquelle sont stockées une table de correspondance comprenant une liste d’index, à chacun desquels est associé un espace mémoire, une table d’adressage de niveau zéro, une table d’adressage de niveau un, une table d’adressage de niveau deux, une table d’adresse de niveaux, - un gestionnaire d’espaces (14) de la table de correspondance étant configuré pour déterminer un index libre dans la table de correspondance, lorsqu’un espace mémoire de la table de correspondance se libère ou se remplit, modifier l’octet stocké dans chaque zone mémoire de chaque table d’adressage associée à l’index.
