摘要
提出了一种基于OMAPL138的电平服务器的设计方案,介绍了电平服务器在交换机系统中的应用。选用TI公司的OMAPL138作为主处理芯片,在此基础上给出了系统硬件结构及外围电路设计,描述了系统具体实现方式。分析了软件设计,详细分析了实时电平算法处理和基于DSPLink的通信机制,该设计可以同时处理多达1 024路的音频信号,为多路语音电平显示提供了解决方案。
This paper puts forward a design scheme of level server based on OMAPL138, and introduces the application of level server in switch system. The OMAPL138 produced by TI Corporation is selected as the main processing chip. The hardware frame and peripheral circuit design are presented, and the implement method of system is introduced. The software flame is analyzed, and the realtime level algorithm and the conmmnication mechanism based on DSPLink are discussed. In this design, up to 1024 channels of PCM can be processed simultaneously. The solution is provided for display of nmlti-channel voice signal.
