摘要：
The present invention relates to the computing method and Huffman computing circuits for improving the correctness and efficiency of the nonlinear inverse quantization when the MPEG-2 AAC (Advanced Audio Coding) or MPEG-4 AAC algorithm which is used as an audio compression algorithm in multi-channel high-quality audio systems is implemented on programmable processors. In accordance with the present invention, while the architecture of the existing digital signal processor is reused, the performance can be improved by means of the addition of Huffman decoder and bit processing architecture. Accordingly, to design and change the programmable processor can be facilitated.
