Abstract

La présente invention concerne un dispositif de commande de comptage. Le dispositif comporte un dispositif engendrant un signal de temps 12, un dispositif de commande par microprogramme 2, 3 comportant un registre adresses 2 commandé par le signal provenant du dispositif 12 et une section adresses qui décode la teneur du registre adresse 2 et amorce les lignes adresses correspondant à plusieurs stades de traitement et une section emmagasinant un microprogramme 3 qui sort des instructions microprogrammées et l'adresse de l'instruction suivante et un dispositif comptage/opération 9, 10, 13, 16, 17, 18 qui effectue une opération de comptage sous la commande des instructions provenant de ladite section d'emmagasinage de microprogrammes 3 et comporte un dispositif arithmétique 16 et un registre 18 pour emmagasiner une information de comptage, une opération de comptage étant effectuée après une pluralité de stades de traitement. Le dispositif est utilisé dans les calculateurs de bureau.
