摘要
以G.729AB为基础,归纳出几种优化方法,使VOIP语音编解码算法能以纯软件的方式在ARM920T上实现。详细介绍了优化的步骤及准则。以模拟数据给出优化结果,并成功在S3C2440开发板上实现。
Based on G.729AB codec algorithm, several optimization methods are summarized. The steps and rules for optimization are introduced in detail. The optimization results are given based on the simulation data. The optimized code runs on S3C2440 evaluation successfully.
