摘要
叙述了MPEG-1LayerⅢ音频压缩编码系统中的量化和反量化模块算法原理及其编解码器的工作过程,并在此基础上结合TMS320c54x系列DSP的指令特点,针对反量化模块提出了一种快速优化算法.
This paper presents the general situation of audio compressing coding and introduces the keystone of MPEG-1 audio reducing coding. Decoding process could be known from this paper. A fast optimized arithmetic based on the character of DSP will be offered in the IQ module.
