在Xilinx开发环境ISE13.2上用MIG产生的DDR3 SDRAM控制器，里面生成了Core，可用于DDR3读写控制(On the Xilinx development environment ISE13.2 generated with MIG DDR3 SDRAM controller, which generates the Core, DDR3 can be used to read and write control)

M25P64-SPI-FLASH芯片的FPGA控制程序，已仿真验证(M25P64- SPI- FLASH chip FPGA control program, simulation)

连乘,乘法可以用简单的for循环，我这里用的是移位寄存器来做，而且是用来两个移位寄存器(this is a tool that function is multiplay,it use a special way to do multiplay .it will teach you the how to use labview )

伪随机m序列VHDL代码，生成多项式为1+x+x^7 (203)，包括代码文件.vhd和模块文件.bsf以及仿真波形，可直接添加到工程中使用。

wm8731的使用，用于音频信号的采集或者产生(wm8731 use for audio signal acquisition or produce)

build a tv box on fpga cyclone 2

利用FPGA采集按键，加了消斗。其实跟单片机的效果差不多。-The use of FPGA collect keys, plus the elimination fighting. In fact, almost with the effect of SCM.

说明：  vhdl code for full adder

该程序描述并且模拟和实现了了一个摩尔有限状态机的功能和作用(The program describes the simulation and the function and role of a mole finite state machine)

本代码介绍了使用VHDL开发FPGA的一般流程，最终采用了一种基于FPGA的数字频率的实现方法。该设计采用硬件描述语言VHDL，在软件开发平台ISE上完成，可以在较高速时钟频率（100MHz）下正常工作。该设计的频率计能准确的测量频率在1Hz到100MHz之间的信号。使用ModelSim仿真软件对VHDL程序做了仿真，并完成了综合布局布线，最终下载到芯片Spartan-II上取得良好测试效果。-the code on the FPGA using VHDL development of the general process, finally adopted a FPGA-based digital frequency method. The design using VHDL hardware description language, the software development platform ISE completed, the higher speed clock frequency (100MHz) under normal work. The design of the frequency meter can be accurately measured in a frequency of 100MHz between Hz signal. Use ModelSim VHDL simulation software to do the simulation process, and completed a comprehensive layout cabling, downloaded to the final chip Spartan-II made good on the test results.
