DE2 开发板上，NIOS编程。对SD卡以及USB的读写操作的实例。我的代码及工程绝对完整！代码其实是Verilog编写的。-DE2 development board, NIOS programming. On the SD card and USB examples of read and write operations. My absolute integrity of code and works! Verilog code

在de2上用niosii实现fat文件系统源代码，可以实现文件的读写操作，介质为sd卡。-In the de2 on the file system using niosii to achieve fat source code, the file read and write operations can be achieved, the medium for the sd card.

DE2 音频处理 从SD卡读去音乐数据在做相应的处理，通过 音频输出口播放 同事可以从音频输入口加入相应的音乐 也可以从MIK口输入音频-DE2 -DE2 audio processing time from the SD card to do the music data in the processing, I play through the audio output from the audio input of my coll

本程序有verilog语言开发而成，实现对于sdcard的读写功能-This program with Verilog language development, the realization of the sdcard read and write functions
