这是一个很好的基于verilog的串口通信422模块，已经经过多次验证，绝对可靠，可直接使用，本人已在工程中多次使用，无误差(This is a good serial communication based on Verilog 422 module, has been repeatedly verified, absolutely reliable, can be used directly, I have repeatedly used in the project, no error)

说明：  希望对VHDL的学习大家有帮助，望大家指出错误，浮想交流！(We want to learn VHDL help, hope you point out an error, daydreams exchange!)

使用verilog HDL写的sdram(SDR)的控制器源代码，具有很好的可移植性，试验的例子已经通过QuartusII 9.0编译通过，可以运行在cycloneII上(Controller source code using verilog HDL written in the sdram (SDR), has good portability, test examples via the QuartusII 9.0 compiler, you can run in cycloneII)

能够完美产生数字地面电视（DTMB）的信源的程序。帧头模式为模式一。信道可选择，信号加入频偏，延时，后经滤波器后输出。(Able to produce perfect digital terrestrial television (DTMB) of the source program. Mode is the mode a header. Channels to choose from, the signal adding offset, delay, after the filter output.)

stm32与fpga之间的通信，协议是SPI的，可双向通信（双向通信需要自己例化，只例化了fpga到stm32）(Communication between STM32 and FPGA, the protocol is SPI, two-way communication (two-way communication needs to be taken as an example, only FPGA to STM32))

基于FPGA设计的经典打砖块小游戏。游戏简单易玩。(FPGA design based on the classic Arkanoid game. Game easy to play.)

FPGA实现基于cordic算法的指数函数的程序(FPGA implementation of an exponential function program based on the cordic algorithm)

ppm调制的verilog代码 可实现ppm调制(ppm modulation verilog code ppm modulation)
