Method and system decoding audio data with selective power control

摘要

Provided is an audio data decoding system and method that may selectively transfer compressed audio data from a top system to at least one audio input buffer of a separately provided and/or separately power management controlled subsystem, restore the compressed audio data to digital pulse code modulation (PCM) data using an audio decoding unit of the subsystem, convert the digital PCM data to analog PCM data or an audio output signal, and output the converted audio output signal.
