Abstract

Sistema para proveer transiciones entre los modos operativos de un dispositivo. El sistema incluye un método para proveer transiciones entre un modo privilegiado y un modo no privilegiado. El método comprende ejecutar una aplicación en el modo no privilegiado, generar una interrupción para requerir los servicios de una función privilegiada, y transitar al modo privilegiado para ejecutar la función privilegiada, ejecutándose la función privilegiada como parte del mismo camino de ejecución que la aplicación.
