Description
Summary:As the widely application of digital multi-media technology, G.729 has become one of the most popular audio standards. In this paper, the TMS320DM6446 which is a Davinci-based multi-core processor is chosen as our platform. We present our implementation method of G.729 algorithm which is compatible with eXpress DSP algorithm interface standard - digital media (xDAIS-DM, also called "xDM") to exploit the advantage of Davinci technology. Then we evaluate the performance of G.729 algorithm in our platform. The results show that G.729 codec can replay a high quality of speech.
