摘　　要：ETSI发布的全数字集群系统TETRA是一种先进的移动通信系统。阐释并优化TETRA中的ACELP语音编码算法是应用领域中的重点。为了能在TI DSP上实时实现ACELP,算法采用全汇编实现,着重研究了ACELP算法的汇编化和关键内容的实现并优化。最后达到了出色的性能和实验结果。The digital trunked system TETRA,defined by the European Telecommunications Standards Institute（ETSI）,is one of the most advanced mobile communication systems today.Firstly,this paper describes the ACELP coding algorithm simply which is adopted in the TETRA codec.In order to implement the ACELP algorithm real-time on TI DSP,we realize ACELP algorithm by using all assemble language.This paper will introduce how to use all assemble language to realize and optimize ACELP algorithm.At last,the corresponding performance and an experiment result will be given.
