摘　　要：介绍了语音编解码芯片TLV320AIC23B在DM642处理器语音接口McASP上的应用,完成了codec驱动程序的设计。在RF5软件框架下,采用多线程方式在DM642上实现了G.723.1语音编解码算法。该语音压缩系统性能测试良好,有很好的扩展性。The connection of TLV320AIC23B to the voice interface MeASP of the DM642 is designed. The codee driver design is completed on the basis of hardware. Under RF5 software framework, multiple threads are used to achieve the G.723.1 speech codec algorithm on the DM642. The performance of the speech compression system tests well, and the system has good expansibility.
