(FR) PROCÉDÉ POUR AMÉLIORER LA ROBUSTESSE D’UNE MISE À JOUR DE MICROPROGRAMME EN PLACE
Abstract:
(EN) An image update apparatus for updating an image, stored by a device with a memory with a plurality of pages, configured to: construct a replacement image section; identify, based on pre-defined overwrite types, an overwrite type that will be made to a page by writing the replacement image section to the memory; and record that the replacement image section for the identified overwrite type has been constructed for that page.
(FR) La présente invention concerne un appareil de mise à jour d’image servant à mettre à jour une image, stockée par un dispositif ayant une mémoire munie d’une pluralité de pages. L’appareil est configuré pour : construire une section d’image de remplacement ; identifier, sur la base de types d’écrasements prédéfinis, un type d’écrasement qui sera appliqué à une page lors de l’écriture de la section d’image de remplacement dans la mémoire ; et enregistrer le fait que la section d’image de remplacement pour le type d’écrasement identifié a été construite pour cette page.
