Abstract: An implementation of multi-channel full-duplex 16kbps CVSD voice codec by the DSP chip TMS320VC5509 of TI. Inc. is proposed in this paper. The design details of the CVSD algorithm is given too. Using embedded system based on MPC860 of Motorola Inc., a method of extending the DSP application filed is brought forward and might provide some valuable reference to the other applications of DSP.
