Abstract: 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.
