Abstract:
In a dual processor mobile device one processor is a radio processor and one processor is an application processor, the mobile device further including a polyphonic audio chip, a method and apparatus for audio control, the method having the steps of: connecting the polyphonic audio chip between the controller and a highly integrated audio codec; connecting the radio processor to the highly integrated audio codec; controlling the highly integrated audio codec from the radio processor; and coordinating between the application processor and the radio processor to allow the radio processor to control the highly integrated audio codec through the radio processor.
