Abstract

DISPOSITIVO DE TRATAMIENTO DE DATOS. EN UNA LINEA GENERAL (14) DE DATOS CONVERGEN UNAS UNIDADES DE ORDENADOR CENTRAL (10, 10A), UNAS UNIDADES DE MEMORIA (11) Y UNA SERIE DE UNIDADES (12) DE ENTRADA/SALIDA. LAS TRANSFERENCIAS DE INFORMACION ENTRE LOS COMPONENTES SE REALIZAN POR LA LINEA GENERAL (14) EN BLOQUES DISCRETOS; DURANTE UN INTERCAMBIO DE INFORMACION EL QUE DA LA ORDEN DE LEER ESTABLECE UNA CONEXION CON LA LINEA GENERAL, CONVIRTIENDOSE EN UN NEXO MAESTRO. LA UNIDAD QUE RESPONDE RECIBE EL NOMBRE DE NEXO SUBORDINADO. DE ESTA FORMA SE PUEDE REDUCIR AL MINIMO EL NUMERO DE LINEAS DE LA LINEA GENERAL DE DATOS (14).
