Patent ID: 8359410

Claim:
A method of processing audio data in a hand-held electronic device, comprising: sending a quantity of audio data from a host subsystem comprising a host processor and a memory device to an electronic storage in an audio subsystem, the quantity being large enough to allow the host subsystem to enter and exit a low power mode; entering the host subsystem into the low power mode; processing the audio data stored in the electronic storage of the audio subsystem via an audio processor of the audio subsystem; sending the processed audio data to an output device coupled to the audio subsystem; transferring second audio data from a communications device coupled to the audio subsystem to the electronic storage of the audio subsystem while the host processor is in the low power mode; processing the second audio data stored in the electronic storage of the audio subsystem using the audio processor of the audio subsystem while the host processor is in the low power mode; and sending the processed second audio data to the output device coupled to the audio subsystem.
