Audio management in a dual processor environment

摘要

In a dual processor mobile device one processor being a radio processor and one processor being an application processor, the mobile device further comprising a polyphonic audio chip, a method of audio control. The method comprisies the steps of: connecting the polyphonic audio chip between the controller and a highly integrated audio codec having a voice codec, a multiplexer and an amplifier; connecting the radio processor to the highly integrated audio codec; controlling the highly integrated audio codec from the radio processor; and synchronizing the application processor and the radio processor by having the application processor control the highly integrated audio codec through the radio processor. The synchronizing step sends all control commands from the application processor through the radio processor, where the radio processor receives the commands and generates an appropriate command to the highly integrated audio codec.
