摘要
首先介绍了MPEG－2音频laverⅢ（MP3）的解码算法，详细地叙述进行定点C语言仿真的技巧。基于TI公司的’C549DSP芯片进行汇编工作，在TMS320G549EVM板上实现了网上MP3文件的连续播放，效果满意。经过对算法和程序的优化使所需的运算量和存储空间都很低，使能在TI公司的低价型’C5402DSP上实现。
A study on MPEG-2 Audio layer Ⅲ (MP3) algorithm is described firstin this paper, then the skill of the fixed point C simulation has been discussedin detail. The main points of this praper are real time MP3 continuous decodingimplementation on TMS320C549 EVM board, the result is ideal. Through the optimization of the operational quantity and storage capacity,so the cheap chipTMS320C5402 DSP is ideal candidate.
