摘　　要：文中先简要介绍了RapidIO三层结构和AC_LINK数字接口协议。结合两者的特点,提出了基于RapidIO的音频传输系统的总体框架和具体设计实现方案。本设计以Xilinx KC705开发板为平台,选用MPC8641D完成板级验证。实验结果表明,本系统能够实时采集传输音频数据,并具有可靠性高、可移植性强、易于升级和工程实现的优点。The Rapid IO three layer structure and AC_LINK digital interface protocol are briefly introduced in this paper. Combined with the characteristics of the two,the overall framework and the specific design and implementation scheme of the audio transmission system based on Rapid IO is proposed. With the platform being Xilinx KC705 development board and the board level verification is completed on MPC8641 D. The experimental results show that the system can collect and transmit audio data in real time,and has the advantages of high reliability,portability,easy upgrade and implementation.
