摘要： 随着语音业务越来越趋于多样化，传统的DSP技术只能简单地对语音进行处理，不能完全胜任业务的多样性。该文介绍了一种利用通信处理芯片MPC860和DSP芯片TMS320VC5509实现多路实时语音通信的方案，并主要讨论了其关键模块QMC驱动。该方案已经得到了应用，能够较好地满足多通道、多路共听的实时语音业务需求。

Abstract: As the voice services become more and more diversified, the traditional DSP techs cannot satisfy the complex service requirements because they can only deal with the voice data simply. This paper presents a solution based on the communication processor MPC860 and the DSP chip TMS320VC5509 to realize a multi-channel real time voice communication design, and mainly analyzes the QMC driver as the key module. This solution has now been used in practice, and can satisfy the requirements of multi-channel communication and multiple voices mix well.
