| Abstract: | 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. |
