基于DSP的mp3解压缩的完整方案

This paper describes the techniques used in the non-linear

dequanTIzaTIon process of MP3 (MPEG audio, Layer III)

decoding, with Motorola Star*Core DSP (MSC8101). The

method introduced here is more than five TImes faster than

calling tradiTIonal mathematics library, yet achieves a high level

of accuracy that conforms to the ISO/IEC 13818-4 standard

[2]. Memory consumption of this method is considerably low

and is very suitable for DSP implementation of the MP3

decoder in real-time.
