Abstract

EL PROCESADOR ESTA ADAPTADO EN ESPECIAL AL MICROCODIGO DE MANERA QUE LA EJECUCION DE UNA INSTRUCCION ESTANDAR CARGADA EN LA ZONA DE ALMACENAMIENTO DE USUARIO SE BLOQUEA SI EXIGE UN ACCESO DE LECTURA O ESCRITURA AL CONTENIDO DE LAS POSICIONES DE MEMORIA. EN LA ZONA DE ALMACENAMIENTO DEL SISTEMA OPERATIVO SE DISPONE DE UNA TABLA DE ACCESO A LA ZONA DE MEMORIA EN LA CUAL SE DEPOSITA EL ESPACIO DE DIRECCIONAMIENTO ADMISIBLE POR CADA ZONA DE MEMORIA DE APLICACIONES PARA LAS INSTRUCCIONES DE ESTAS. POR ULTIMO SE DISPONE DE UNA RUTINA DE PROGRAMAS, QUE ES LLAMADA POR CUALQUIER INSTRUCCION CARGADA EN UNA ZONA DE ALMACENAMIENTO DE APLICACIONES QUE EXIJA EL ACCESO PARA LECTURA O ESCRITURA A UNA POSICION DE MEMORIA, Y QUE ANTES DE EJECUTARSE LA INSTRUCCION COMPRUEBA, MEDIANTE LA TABLA DE ACCESO DE LA ZONA DE USUARIO, SI EL ACCESO SOLICITADO A UNA POSICION DE MEMORIA SE ENCUENTRA EN EL ESPACIO DE DIRECCIONAMIENTO PERMITIDO, O BIEN BLOQUEA LA EJECUCION DE LA INSTRUCCION EN CASO CONTRARIO. LA INVENCION TIENE LA VENTAJA DE PODER LIMITAR DE MANERA SENCILLA EL RADIO DE ACCION DE UNO O VARIOS PROGRAMAS DE APLICACION EN LA ZONA DE ALMACENAMIENTO DE PROGRAMAS DE APLICACION.
