5位计数器

这是fpga按键消抖的源代码，在很多fpga按键实验中都可以用到，能够进行代码移植。(This is the source code of the FPGA buttons, in many FPGA key experiments can be used, and can carry out code.)

It is Synopsys dmac controller databook

简易数字存储示波器verilog源代码 经过EP2C8Q208C8验证(Simple digital storage oscilloscope verilog source code has been verified EP2C8Q208C8)

This is a demo for TFT LCD LQ091B1LW01(Sharp 9.1inch, 822 X 260) with Spartan-6 FPGA.

用FPGA实现DDS波形发生器。可以实现方波，三角波，正弦波的切换，实现频率的调节。三角波和正弦波均用查表法实现。本文档包括一个主程序的代码，按键和显示的实例化程序代码、调用ROM生成的代码以及正弦波和三角波实现的数据表。

基于FPGA的Verilog语言的智能小车，已经经过测试。(FPGA-based smart car Verilog language, and has been tested.)

4-16译码器，用VHDL编写的，可以直接下载到可编程逻辑器件中(4-16 decoder, written with VHDL, can be directly downloaded to the programmable logic device)

我们的设计是用一个FSM控制器来控制发送什么命令，flash模块判断FSM发送过来的state信号来选择应该执行什么操作，当命令写入或者读出后，会发送一个flag_done命令，这个命令让我们判断上个指令是否完成，如果完成后FAM将发送下一个命令.(Our design uses a FSM controller to control what commands are sent. The flash module judges the state signal sent by the FSM to select what operation should be performed. When the command is written or read out, a flag_done command is sent. This command lets us judge whether the last word is finished or if the FAM will be sent after completion. The next command)
