摘要
该文根据G.729编解码理论和具体解码流程,结合TI公司DSP产品TMS320C6000系列的TMS320DM642、CCS6000集成开发环境以及G.729的硬件实现平台,提出了DSP传送数据给ARM的算法,以及实现G.729解码算法的主要程序,在最后给出了G.729解码的结果。实验表明:该方案能够成功地实现语音解码。该方法具有低延迟、低速率、高语音质量的优点。
Based on the basic theory of the speech coding(LP,VQ,CELP)and the A- B- S technique, combining the TMS320DM642 and the CCS6000, this paper propose the algorithm of the data delivered from DSP to ARM, And the main program of the G.729 decoder, finally, the result of the G.729 decoder has been given. Experiments show that this scheme can successfully implement speech decoding。This method has the advantages of low latency, low rate and high speech quality.
