| Abstract: | The connection of TLV320AIC23B to the voice interface McASP of the DM642 is designed. The codec 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. |
