是使用VHDL语言编写的基于FPGA的uart的源代码！

在Altera芯片2C35F672平台上的FFT程序，采用DSPBuilder5.0，生成Verilog文件。开发环境：QuartusII5.0。-In the Altera chip 2C35F672 platform FFT procedures DSPBuilder5.0, generated Verilog file. Development Environment: QuartusII5.0.

说明：  这是32位移位寄存器，是用verilog编写的，能够实现从1到31位的左或右的移位(This is a 32-bit shift register, is prepared verilog, can be realized from the 1-31 shift left or right)

用FPGA模拟VGA时序、模拟PS/2总线的键盘接口VHDL源代码，基于Xilinx spartan3-VGA FPGA timing simulation, simulation PS/2 keyboard interface bus VHDL source code, Based on Xilinx spartan3

改写四号中断的 自己编的，，，，，，求过啊！！！一个很简单的小程序(Rewrite the fourth interruption of their series,,,,,, begged ah! ! ! A very simple little program)

DE2 VGA控制代码，de2上控制VGA-DE2 VGA control code, de2 to control VGA

采用costas环进行DPSK解调的程序。输入数据速率2.4Kbps，载波频率12KHz，采样率1.6MHz， 输入数据位宽12位，快捕带为799.617Hz(Costas ring using DPSK demodulation process. Input data rate 2.4Kbps, carrier frequency 12KHz, sampling rate 1.6MHz, the input data 12 bits wide, fast catching band is 799.617Hz)

verilog 模糊PID 通过修改MIF文件 可以完成单个参数整定(FUZZY pid by verilog HDL)

32位存储器Verilog附带test文件，可以在modulesim仿真 还有加法、减法器，译码器等常用Verilog器件，都附带仿真test。(Memory test with Verilog)

一个用Verilog编写的编帧、解帧及码速匹配的程序，相当经典(Verilog prepared with a series of frames, frames and solutions yards speed matching procedures, rather classic!)

verilog数字系统设计，一本很好的verilog学习的书籍，很适合初学者(verilog digital system design, a good verilog learning books, it is suitable for beginners)
