Abstract

EL INVENTO SE REFIERE A UN PROCEDIMIENTO Y UNA DISPOSICION PARA ASEGURAR CODIGOS DE DATOS ARCHIVADOS EN UN ALAMACENADOR (1A) DE CODIGO DE DATOS ANTES DEL ANALISIS QUE SE CIERRA POR LAS SEÑALES DE SALIDA DEL ALMACENADOR DE CODIGOS DE DATOS RESPECTO DEL CONTENIDO DEL ACUMULADOR DE CODIGOS DE DATOS. CON ARREGLO AL INVENTO CONTACTA CON LAS SALIDAS DEL ALMACENADOR DE CODIGOS DE DATOS UNA DISPOSICION DE BLOQUEO (4) CONTROLADA POR UNA DISPOSICION LOGICA (9) DE BLOQUEO QUE BLOQUEA LA SALIDA DEL CODIGO DE DATOS, TAN PRONTO COMO LOS DATOS DE CONTROL SUMINISTRADO NO COINCIDEN CON LOS DATOS DE CODIGO.THE INVENTION REFERS TO A PROCEDURE AND A PROVISION FOR SECURING DATA CODES FILED IN A DATA CODE STOREHOUSE (1A) BEFORE ANALYSIS THAT IS CLOSED BY THE OUTPUT SIGNALS OF THE DATA CODE STORE FROM THE CONTENT OF DATA. IN ACCORDANCE WITH THE INVENTION CONTACT WITH THE OUTPUTS OF THE DATA CODE STORAGE A LOCKING PROVISION (4) CONTROLLED BY A LOGICAL LOCKING PROVISION (9) THAT BLOCKS THE OUTPUT OF THE DATA CODE PROVIDED AS SOON AS THE CONTROL DATA PROVIDED NOT WITH THE CODE DATA.
