基于AES10光纤总线多功能音频控制系统的研究

Research on multi-function music control system based on the AES10 optical bus

采用FPGA为控制核心的多功能音乐控制系统,对声卡的数据进行光纤传输,通信符合AES10协议。通过FPGA的强大功能对其数据进行编解码,再与多达32个音频设备(包括左右声道)进行IIS协议通信。本设备完成了多功能音乐控制设备的功能,并在Quartus II环境下做了综合与仿真,达到了预期稳定的效果,为将来的音乐与计算机的有机结合提供了良好的平台。

This paper introduces the multi-function music control system with FPGA as the control center.The sound card data transmission using optical fiber,is in compliance with AES10 protocol,encoding and decoding through powerful capabilities of FPGA,and then with up to 32 audio devices（including left and right channels）connected via IIS protocols.The device implements a multi-function music control device prototype, makes a series of simulation,achieves the desired stabilizing effect,and provides a good platform for the combination of music and the computer in the future.
