摘要
基于ARM体系构架和嵌入式Linux操作系统构建了算法平台的硬件和软件结构,并在该平台移植了G.729语音编解码算法。通过对软件优化设计以及采用基于ARM指令集的算法优化策略,对G.729编解码器进行优化,提高了系统运行速度。
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.
