摘　　要：为减小编解码运算复杂度,提出了一种基于DSP的G.729语音编解码算法实现方法,重点对DSP的代码优化作了论述.仿真结果表明,运算复杂度大大降低,在单片TMS320VC5410上完全能够实现G.729语音编解码算法.重建语音具有符合标准的编解码效果.In order to reduce the operational complexity of codec, a scheme for G.729 speech codec algorithm based on DSP is presented, whose code optimization is specially discussed in this paper. The simulated results show the operational complexity is reduced ready and the implementation of G. 729 speech codec algorithm can completely be done with single TMS320VC5410 chip, the synthesized speech has the accordant codec effect with the standard.
