GW48系统电子琴：可控制8个音节，4种音调 readme中带使用说明

verilog编程语言的讲解，有电子科技大学出版(verilog programming language to explain, there is the University of Electronic Science and Technology Publishing)

基于FPGA DE0以及niosII的射频无线发送程序,采用spi接口操作无线模块nrf24l01(To spi interface operation wireless module nrf24l01 of FPGA DE0, as well niosII RF wireless transmitter program)

自己编写的同步和异步FIFO的verilog代码，验证过，有可靠性(Verilog code of my own synchronous and asynchronous FIFO, verified,and reliable.)

rmii 以太网接口时序源代码，值得开发借鉴的哦(verilog hdl)

bch encoder+decoder 源代码，Flash控制器，通讯都需要用到哦-bch encoder+ decoder source code, Flash controller, communications are needed Oh

正弦信号发生器，用VHDL来完成，抗干扰能力较强，(Sinusoidal signal generator, using VHDL to accomplish, a strong anti-interference ability,)

说明：  SPI协议的芯片验证VIP,用UVM搭建平台验证代码(Chip verification VIP of SPI protocol, build platform verification code with UVM)

4位2选1多路选择器的设计与实现。nexy3开发板。本实验中用Verilog语句来描述。(Xilinx ISE 12.3.nexy3.)

信号处理中所用到的matlab程序，包括LFM,NLFM,BPSK,QPSK等等。(Matlab procedures used in signal processing, including LFM, NLFM, BPSK, QPSK, and so on.)
