| Abstract: | The coding and decoding algorithm of G.729A vocoder and the TMS320C5416 fixed point DSP (Digital Signal Processing) chip are described briefly. Design of hardware and software of short delay G.729A vocoder based on TMS320C5416 is given. Some key techniques and problems in software design process that should be noticed analyzed and summarized are. The test results of real time implementationed are presented in the end. |
