本代码为Altera DE2开发板例程源码（EP2C35F672C6)，quartus II 9.0以上版本均可编译（随板光盘为quartus II 7.2版在9.0以上版本上编译会报错）。本工程实现SD的音频播放器，即通过FPGA控制SD卡，读取SD的音频文件，通过WM8731进行播放。-In this demonstration we show how to implement an SD Card Music Player on the DE2 board, in
which the music files are stored in an SD card and the board can play the music files via its
CD-quality audio DAC circuits. We use the Nios II processor to read the music data stored in the
SD Card and use the Wolfson WM8731 audio CODEC to play the music.
