First Claim
Patent Images
1. An apparatus for reproducing audio data, the apparatus comprising:
- a top system to transfer the audio data;
an audio input buffer to store the audio data received from the top system;
an audio output buffer to store decoded audio data; and
a power controlling unit to control a power supplied to the top system based on at least one of an amount of audio data stored in the audio input buffer that is consumed, and an amount of audio data stored in the audio output buffer that is consumed.

Abstract
A method and apparatus for reproducing audio data using low power are provided. The apparatus may reproduce the audio data by determining a power mode based on a memory resource of an internal memory, and an amount of a memory required for reproducing the audio data, controlling a power based on the determined power mode, and decoding the audio data.
