Patent Images
1. A method for controlling power, the method comprising:
- in an integrated circuit comprising a multimedia processor, said multimedia processor comprising an audio interface and a processing unit;
decoding coded audio data with the processing unit to generate decoded audio data;
storing the decoded audio in memory;
powering down the processing unit; and
providing, with the audio interface, the decoded audio data from the memory to an output, while the processing unit is powered downpowering up the processing unit in response to an amount of decoded audio data to be transferred falling below a threshold amount of decoded audio data.
