Abstract

SISTEMA DE TRATAMIENTO DE ACCESO EN PROCESADOR DE INFORMACION, INCLUYENDO EL PROCESADOR: UN DISPOSITIVO DE ACCESO (10, 11) PARA GENERAR UNA SEÑAL DE PETICION DE ACCESO; UN DISPOSITIVO ACCEDIDO (13) PROVISTO DE MEDIOS DE MEMORIA (30) QUE SON ACCEDIDOS POR EL DISPOSITIVO DE ACCESO (10, 11); Y UNA LINEA GENERAL DE DIRECCION (14) QUE TIENE EL DISPOSITIVO DE ACCESO Y EL DISPOSITIVO ACCEDIDO CONECTADOS CON EL PROCESADOR DE INFORMACION AL MENOS POR LA LINEA GENERAL DE DIRECCION (14). EL SISTEMA DE TRATAMIENTO DE ACCESO ES TRATADO DE TAL MANERA QUE, SI SE PRODUCE UNA PETICION DE ACCESO, CUANDO LA SEÑAL DE PETICION DE ACCESO NO REQUIERE TODOS LOS BITS DE LA LINEA GENERAL DE DIRECCION (14), SE CARGA UN BIT NO UTILIZADO EN LA LINEA GENERAL DE DIRECCION (14) CON DATOS DE ESCRITURA PARA ENTREGARLOS AL DISPOSITIVO ACCEDIDO.
