摘要
该文献基于CPU为三星的S3C2440的Mini2440开发板,设计与开发了以声码器AMBE-2000为核心的低带宽语音通信系统。给出了接口电路,完成内核驱动的编写与调试。实现了通过有线局域网的点对点低带宽实时语音通信。
Based on the CPU for Samsung S3C2440 of the Mini2440 development board,this paper designed and developed a low bandwidth voice communication system,with AMBE-2000 sound vocoder as the core of the system.The interface circuit is provided,and the writing of the kernel drivers and debugging are completed.This paper realized point-to-point low bandwidth real-time speech communications through the cable LAN.
