verilog 万能流水灯

本工程使用A7系列FPGA产生DDS，用DAC0832进行正弦电压输出(In this project, A7 series FPGA is used to generate DDS, and DAC0832 is used for sinusoidal voltage output)

自适应滤波器算法LMS ，的FPGA实现，采用VERILOG实现。(LMS, an adaptive filter algorithm, is implemented on FPGA and VERILOG.)

贪吃蛇程序，用verilog实现，可以运行只要修改一下相应的FPGA芯片类型和VGA接口相应的引脚(Snake program, using Verilog to achieve, you can run as long as the appropriate to modify the corresponding FPGA chip type and VGA interface to the corresponding pin)

基于FPGA的JPEG解码，对开发图片解码的人有用。(FPGA-based JPEG decoding, the development of image decoding useful.)

模拟地铁自动售票机选票、付款、取票、找零等功能，包含软件仿真和硬件响应，可供仿真测试和FPGA验证。(Analog subway ticket vending machine ballots, payment, tickets, give change and other features, including software simulation and hardware response for simulation and FPGA verification test.)

ISE 9.2 serials working

这里面有很多的vhdl的编程的源代码，文件是全英文的，例子丰富(That there are a lot of vhdl programming source code, documentation is in English, and examples of rich)

说明：  Convolutional neural network code for fpga

说明：  vivado软件中的时序约束参考资料，很详细，不同的约束种类对应不同的命令。(vivado-using-constraints)

在fpga中对于pll无法完成的分频，可采用计数方式，本例用状态机实现对时钟的奇数分频。(Pll in fpga can not be completed in the sub-frequency counting method can be used, in this case with the state machine to achieve an odd number on the clock frequency.)
