Abstract
Sistema para invocar una función de privilegio en un dispositivo. El sistema incluye un método que permite invocar una función en un dispositivo, en donde el dispositivo incluye al menos dos modos operativos que comprenden un modo privilegiado y un modo no privilegiado, y la función ejecuta en el modo privilegiado. El método incluye recibir una solicitud desde la aplicación para invocar la función y determinar el modo operativo de la aplicación. El método además incluye invocar la función usando una interrupción, si la aplicación es ejecutada en el modo no privilegiado, en donde la función es ejecutada dentro de la misma tarea que la aplicación. El método además incluye invocar la función directamente, si la aplicación es ejecutada en el modo privilegiado.
