| Abstract: | With the development of digital audio technology,the design of audio interfaces has become of increasing importance.We propose a design of a simple audio interface based on the data transmission protocol of I2S.The interface can transmit data via full-duplex,with a SPI interface integrated to generate control signals.The design has been realized via FPGA,and the resultant interface has been experimentally verified of its ability to coordinate audio data transmission between GARFIELD4 and TLV320AIC23B. |
