Abstract

L'invention concerne l'informatique Un dispositif de transfert de données entre un processeur central 13 et une mémoire à disque 12 comprend essentiellement une mémoire tampon de bloc de données 17, une ligne bus 15, et un émetteur/récepteur 18 qui fait communiquer sélectivement le processeur avec la ligne bus. Cette configuration permet d'adapter une mémoire à disque qui a une cadence de transfert de données élevée, et un processeur central 13 qui a une cadence de transfert de données plus lente. Application aux petits ordinateurs.
