基于CPLD的I^2S语音总线接口

I^2S audio bus interface base on CPLD

本文介绍了利用Xilinx公司的XC9500系列CPLD器件,以I2S接口方式对四路输入语音信号进行处理与传输,并用VHDL进行建模,通过ISE软件仿真得出了比较理想的结果,并在工程应用中使用良好。

This paper introduce some information about CPLD devices of XC9500 series which made by Xilinx company. You can use it deal with and transmit the four pathes audio signal by I^2S data transmission pattern. Additionally, you can use VHDL to modeling. Then,you will receive a ratter perfect result by utilizing the ISE software simulation,and do very well in the project application.
