| Abstract: | Two digital audio interface protocols I2S 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. |
