Abstract

"SISTEMA PARA SOLICITAR UMA FUNçãO PRIVILEGIADA EM UM DISPOSITIVO". Descreve-se um sistema para solicitar uma função privilegiada em um dispositivo. O sistema inclui um método que permite que um aplicativo solicite uma função sobre um dispositivo, onde o dispositivo inclui pelo menos dois modos operacionais que compreendem um modo privilegiado em um modo não-privilegiado, e a função é executada no modo privilegiado. O método inclui receber um pedido do aplicativo para solicitar a função e determinar o modo operacional do aplicativo. O método também inclui solicitar uma função utilizando uma interrupção, se o aplicativo estiver sendo executado no modo não-privilegiado, onde a função é executada dentro da mesma tarefa que o aplicativo. O método também inclui solicitar a função diretamente, se o aplicativo estiver sendo executado no modo privilegiado.
