摘要
简要介绍了TI的定点多媒体处理芯片TMS320DM642的特点、软硬件开发平台及Ogg/Vorbis音频编解码算法。分析了Ogg/Vorbis编解码算法的工作流程,并重点阐述了基于DM642平台的Ogg/Vorbis音频编解码算法的移植。实验结果表明,移植后的Ogg/Vorbis音频编解码算法能够实现音频文件的编解码。
The characteristics of TI fixed-point multimedia processor TMS320DM642, software＆ hardware development platform and arithmetic of Ogg/Vorbis Codec are introduced briefly. The process of Ogg/Vorbis arithmetic is described, and the code transplantation is discussed. Experiment result shows that the transplanted code is capable of coding and decoding.
