为了满足语音信号处理算法实时实现的需要,提出了一种以TMS320DM642为核心的语音处理系统的设计方案。主要介绍了该系统的硬件组成即TMS320DM642的MCASP接口和立体声音频编解码芯片TLV320AIC23B及回声算法在该系统下的实现。实践证明,所设计系统是正确高效的。该系统为研究语音信号的实时处理做出了一定的贡献。
In order to meet the need of real-time implementation of speech signal processing algorithms, a design scheme of speech processing system based on TMS320DM642 is proposed. Mainly introduces the hardware components of the system, that is, TMS320DM642 MCASP interface and stereo audio codec chip TLV320AIC23B and echo algorithm in the system. Practice has proved that the system designed is correct and efficient. The system has made certain contributions to the research of real-time processing of voice signals.
