Patent CA-2285182-A1 (CA)
Inventor: LAWS RICHARD
IPC: G06F17/30
Filed: 1998-03-30
Abstract: On considère ici un système d'exploitation comportant un système de gestion de fichiers permettant l'écriture de données dans un fichier dans une boucle logique de grappes d'emplacements mémoire. L'écriture peut se faire en boucle fermée ou ouverte, avec possibilité de passage d'un mode à l'autre. L'enregistrement avant l'occurrence d'un événement asynchrone se fait en mode boucle fermée. Après occurrence de l'événement asynchrone, les données recueillies dans la partie en boucle fermée sont fusionnées sans solution de continuité avec les données recueillies ultérieurement par manipulation par le système d'exploitation des pointeurs de grappes. Grâce à une telle structure générale de manipulation des fichiers dans le système informatique, on dispose de bien plus de place en mémoire pour l'enregistrement en boucle fermée. En fait, il est possible de recueillir plusieurs minutes de vidéo en qualité cinéma. En outre, étant donné que c'est le système de gestion des fichiers qui assure le stockage des données, il n'y a besoin d'aucune application spécifique pour mettre les données enregistrées sur un support physique d'enregistrement. Un tel système de gestion de fichier convient à toute application recueillant des données dans la perspective de saisir l'occurrence d'un événement asynchrone. Les applications considérées portent notamment sur l'enregistrement de films vidéo, la surveillance, la collecte de données de test, et d'autres types de systèmes qui ont besoin d'enregistrer des événements précédant une condition spécifique de "déclenchement" aléatoire, lesquels événements peuvent nécessiter de grandes quantités de mémoire.
