摘　　要：G．723．1协议是ITU－T（国际电信联盟）为多媒体通信制定的双速率语音编码的国际标准。TM1000是一种带有VLIW（超长指令字）结构的多媒体处理器，可应用在可视电话、会议电视、JPEG、MPEG－1等通信领域。介绍一种采用TM1000处理器平台实时实现符合G．723．1协议的语音编解码器。The G.723.1 Recommendation is the international standard of double-bit rate speech coding which is drawn up by ITU-T for multimedia communication multimedia processor TM1000 with VLIW structure. It can be used in the multimedia communication fields such as videophone, videoconference, JPEG, MPEG-1 etc. The implementation of real time G.723.1 speech coder based on the TM1000 is introduced in this paper. The result shows that this speech coder and decoder fully meet the needs of the G.723.1 multimedia terminal.
