Abstract: According to ITU-T Recommendation G.723.1we realize parallel speech coder/decoder compressing on 16 ways on single TMS320C6201 and finish crucial software of digital recording transfer chip designment.According to the features of the G.723.1 algorithm and the architecture of C6201,the algorithm,C programming and .asm programming are optimized so as to reduce computation complex and memory size. The chart of coder/decoder performance was presented. Finally we make all test vectors. ;;;
