| Abstract: | In this paper, it described the structures of hardware and software needed by algorithm which is based on the architecture of ARM and embedded Linux operation system, and G.729 speech codec is transplanted in this platform. In the application of this algorithm, through optimizing design of the sofeware and by the algorithm optimization strategies based on ARM command sets, the G.729 codec is optimized and improve the move speed of the system. |
