资料介绍

为满足现代汽车电子系统成本低、灵活性高和扩展性强的设计要求,基于FPGA,设计了一种I2S音频数据处理电路。以I^2S协议为基础,采用ZYNQ-7000开发平台,为音频解码芯片AUDU1761与CPU完成音频数据通信,实现了音频输入和输出功能。为音频解码设计独立时钟,解决了传统设计中占用CPU过多的问题,同时可以降低失真。仿真结果表明,电路设计合理,可实现对音频数据的接收和发送功能。

In order to meet the low-cost,flexible and extensible design demands of modern automotive electronic system,a hardware circuit which adopt the I^2 S agreement is designed based on FPGA.In ZYNQ-7000 development platform,the audio decoding chip AUDU1761 sets up data communication with CPU by this circuit.A clock is designed for decoding chip separately to solve the problem of high CPU usage which provides the clock by CPU,it can reduce distortion at the same time.The circuit is proved to be correct by the function simulation,the function of audio data receiving and sending can be completed greatly.
