摘要
针对VoIP交换机语音网关的需求,实现了基于XDAIS标准的G.729A算法。结合TI DSP处理器C55x的特点对算法进行优化,实现单片TMS320VC5510中12路语音编解码,在此基础上完成了支持96路话音的VoIP语音网关的设计,并已成功应用到多种型号的军用语音交换机中。
The G.729 A algorithm based on XDAIS is realized to satisfy the demands for the voice gateway of VoIP switch. The algorithm is optimized combined with C55 X platform of TI DSP processor to realize 12-channel voice encoding and decoding in a single TMS320VC5510. Based on this result, a VoIP voice gateway supporting 96-channel voice is completed, and it has applied to military voice switches with several types.
