摘要
详细分析了ITU TG·729CS ACELP语音编解码算法的原理,针对算法特征及DSP体系结构特点,提出了一些有效的优化措施,在TITMS320VC5410DSP平台上实现了该算法的实时编解码.该系统的实现可应用于数字语音存储和网络多媒体通信系统等领域.
After studying the principle of ITU-T G·729 in detail, some optimized methods are presented according to the characters of the algorithm and DSP, which can reduce the calculation burden. Its implement scheme founded on the hardware system composed of DSP TMS320VC5410 is also presented. This design can be widely used in the digital voice storage system and network multimedia communication system.
