Abstract

Dispositif et procédé pour le transfert de données d'une unité de traitement de données. Le dispositif est conçu pour répondre à une instruction microprogrammée pour transférer au moins des parties de mots de donnée d'une mémoire de l'unité à un registre déterminé d'une pluralité de registres récepteurs par des moyens comprenant un registre intermédiaire à décalage. Le registre intermédiaire est constitué de deux moitiés, droite et gauche, de la dimension d'un mot de donnée lue en mémoire, et par rapport auxquelles lesdits moyens permettent le transfert de mots de donnée séquentiellement de la mémoire au registre intermédiaire et de ce registre au registre récepteur suivant des champs qui caractérisent l'instruction de transfert à opérer avec conversion de forme de mots à 9 bits en mots à 8 bits. Application : transfert de données entre systèmes de traitement incompatibles par construction.Device and method for transferring data from a data processing unit. The device is designed to respond to a microprogrammed instruction to transfer at least parts of data words from a memory of the unit to a determined register of a plurality of receiving registers by means comprising an intermediate shift register. The intermediate register consists of two halves, right and left, of the size of a data word read in memory, and with respect to which said means allow the transfer of data words sequentially from the memory to the intermediate register and from this register to the following receiving register fields which characterize the transfer instruction to be operated with conversion of the form of 9-bit words into 8-bit words. Application: transfer of data between processing systems incompatible by construction.
