摘要
介绍了当今常用的两种数字音频接口协议I2S及S/PDIF,并分析了这两种接口的实现技术。在此基础上,提出了一种基于AMBA总线的,同时支持这两种协议的数字音频接口IP核设计方案,并利用Xilinx FPGA实现了这部分硬件电路,仿真结果验证了该方法的可行性。
Two digital audio interface protocols FS and S/PDIF are introduced. The implementation technology of the two digital audio interface protocols is analyzed. An implementation method which supports both the two protocols simultaneously is presented based on the AMBA bus protocol. And the hardware circuits of this part is implemented on the Xilinx＇s FPGA. The simulation results show that this method is feasible.
