里德所罗门编码器

uart implementation and documentation, this describes the basic steps in building your own uart module on verilog and programming them on an fpga device

RS（255，223）编码器，已实际运用到产品中(RS (255,223) encoder has actually applied to products)

VHDL语言实现两个人掷骰子游戏，最多6次，大者胜则结束游戏并在点阵上显示，一直平手则一直进行直到达到6次。(Achieving the dice game between two people by using VHDL language.The maximum number of times is 6.The game will over when there is a biger one in one time,otherwise,the game will continue until the time of the game is up to 6.)

AD7991_7995_7999转换器说明(4-Channel, 12-/10-/8-Bit ADC with I2C-Compatible Interface in 8-Lead SOT-23)

程序设置了fpga 的 5x5点阵驱动程序，代码相对比较简洁，这个程序可以作为fpga输出控制，驱动稳压芯片工作，进而点灯

使用verilog语言编写的异步串口模块，带有16级深的FIFO，它与DSP28335的SCI相似，可以帮助初学者更快地理解FPGA和DSP的硬件结构和编程思路(Use verilog language of asynchronous serial port module, FIFO with deep level 16, it was similar with DSP28335 SCI, can help beginners to understand faster the FPGA and DSP hardware structure and programming ideas)

2004 SNUG of systemverilog

说明：  本设计是基于FPGA的高速并行接口通信接口和协议设计，该设计使用的是8 位并行接口，通过配置FPGA的FIFO寄存器保证了在高速并行下的数据稳定性，在 最终的测试中，该协议能够稳定传输的速度为80Mbps。(This design is based on FPGA high-speed parallel interface communication interface and protocol design, the design uses 8 Bit parallel interface ensures the data stability under high-speed parallel by configuring the FIFO register of FPGA. In the final test, the protocol can stably transmit at 80 Mbps.)

说明：  插值滤波器,用于音频解码调制解调,滤波器系数用移位相加实现(Interpolation filter, audio decoder for modulation and demodulation, filter coefficient shift combined with the realization of)

DDR2控制器设计原码,可以在FPGA上测试通过,并对外部的ddr memory进行读写访问.(DDR2 controller design of the original code, can be tested through the FPGA, and external ddr memory read and write access.)
