摘要
在分析自适应多速率宽带语音编码标准(AMR-WB)编解码技术的基础上,结合MIPS32 4Kec处理器的结构特点,完成算法的移植工作,并采用精简与汇编相结合的方式对系统进行优化,测试结果表明该系统具有较高的实时性和语音质量。
Based on the instruction of Adaptive Multi-Rate Wideband speech coding standard （AMR-WB）and the MIPS32’s structural features,this paper completes the algorithm transplantation on this platform,and optimizes this system with the way of reduce and assembler.The results of test show that this system achieves high real-time property and speech quality.
