Abstract

Unité de commande de mémoire tampon à disque dynamique. L'invention concerne un perfectionnement des systèmes de traitement de l'information, et particulièrement un dispositif pour optimiser le débit des systèmes utilisant des mémoires à disque magnétique comme mémoire auxiliaire. On a trouvé que leurs performances étaient limitées par la mémoire principale à tore et le temps d'accès au disque. Les remèdes classiques sont loins d'être optimum. Alors que ces mesures ont permis de réduire les délais de charge du système en tâches, elles sont de valeur limitée dans les systèmes à usagers multiples, à grande base de données, où un grand nombre de fichiers est toujours actif. L'invention prévoit un ensemble de commande programmable d'une mémoire à disque et une unité de commande comprenant un microprocesseur, une mémoire à accès sélectif RAM utilisée en tampon pour les données résidant dans le disque d'antémémoire utilisé par un système de traitement de données (STD) et une voie de donnée pouvant être configurée (CDP) qui couple le STD à l'unité de commande de disque. Le microprocesseur est programmé pour fournir un accès rapide du STD aux données résidant dans le disque en commandant la CDP de façon à maintenir une antémémoire de données résidant dans le disque dans la RAM. Application aux systèmes de traitement de données.
