Abstract

Dispositif de conversion du format des données pour convertir ces données du format décimal codé binaire étendu au format décimal codé binaire condensé dans un processeur numérique. Le dispositif 14 comprend un circuit de décalage de multiplets coopérant avec le circuit de décalage de bits 35 et un circuit de conversion de format pour convertir simultanément un groupe de multiplets reçus sur le bus 13 en format étendu, en multiplets dans le format condensé transmis en parallèle sur le bus 15, et réciproquement. Une telle conversion de format simultanée de plusieurs multiplets permet d'exécuter l'opération de condensation ou de decondensation d'une manière bien plus rapide que dans les processeurs classiques à conversion d'un seul multiplet à la fois.
