摘要
介绍了数字信号处理器和与音压缩标准。分析了以实现多通道声码器的设计要点,设计了一个用TMS320C6201ITU-T G.723.1C6201于电话系统的多通道实时语音编解码子系统。该系统实现了包括附录在内的全部功能,通过了的所有测试矢量。在一片IPITU G.723.1AITU主频为的上,可以全双工实时处理路话音。
A real-time implementation of multi-channel full-duplex ITU-TG.723.1 is presented in this paper. The number of channels provided by one chip of TMS320C6201 running on 200MHz clock can reach as high as 16.This system has fulfilled all functions of ITU-T G.723.1 including those of annex A and passed bit-exact verification with all of the ITU test vectors.
