Abstract:

We present a design of a PCII2S audio system based on FPGA.By combining the PCI soft core,FIFO,and the designed interface circuit in FPGA,we implement such buses as PCI,I2C,and I2S in this FPGA system.We also implement the function of audio date transmission and playing by using the stereo audio codec Tlv320aic23b with FPGA.The system makes full use of the resources on FPGA and its characteristic of reprogrammability to reduce the complexity of the hardware circuit design.
