音频系统中霍夫曼解码算法改进

An Optimal Algorithm in Huffman Decoding Module of the Audio System

文中对在MPEG-1音频系统中的快速霍夫曼解码算法进行有效的改进。通过码表的变换,它可以快速定位码表范围,从而大大提高查找速度。这对于提高整个音频系统的执行效率起着至关重要的作用。

In this paper, an optimal algorithm in Huffman decoding module of MPEG-l audio system is presented. The range of the code table can be fastly determined and the looking--up speed also can be improved greatly hy conversion of the Huffman table. That is important to the improvement of the actual efficiency in the whofe audio systerm.
