这是我自己编写的三分频，也就是奇数分频，占空比为1：1，当然如果需要其它奇数分频，只要将程序里面的N和counter修改即可...

使用FPGA测量频率大小，并且在数码管上进行显示(Frequency measurement using FPGA and display on digital tube)

ISE环境下Verilog编程实现机械按键去抖(ISE Verilog programming environment under mechanical debounces)

VGA驱动及显示程序，用Verilog编写代码实现VGA的驱动和显示，并且提供了测试程序Testbench通过测试能得到正确的时序波形。(the source code for driving VGA and displaying the images,the testbench was offered.)

说明：  Digital pre-distortion (DPD) is an advanced digital signal-processing technique that mitigates the effects of power amplifier (PA) nonlinearity in wireless transmitters. DPD plays a key role in providing efficient radio digital front-end (DFE) solutions for 3G/4G basestations and beyond. Modern FPGAs are a promising target platform for the implementation of flexible wireless DFE solutions, including DPD.

说明：  FPGA对系统50M时钟进行分频。FPGA最基本功能基础(FPGA Verilog program, key detection, program jitter elimination, jitter elimination, delay detection keys)

用键盘控制FPGA，再由FPGA控制VGA显示器是好东西-Use the keyboard to control FPGA, and then by the FPGA to control VGA display is a good thing

说明：  高斯最小频移键控（Gaussian Filtered Minimum Shift Keying），这是GSM系统采用的调制方式。数字调制解调技术是数字蜂窝移动通信系统空中接口的重要组成部分。GMSK调制是在MSK（最小频移键控）调制器之前插入高斯低通预调制滤波器这样一种调制方式。GMSK提高了数字移动通信的频谱利用率和通信质量。(Gauss Filtered Minimum Shift Keying is a modulation method used in GSM system. Digital modem technology is an important part of air interface of digital cellular mobile communication system. GMSK modulation is a method of inserting a Gaussian low-pass pre-modulation filter before the MSK (minimum frequency shift keying) modulator. GMSK improves the spectrum utilization and communication quality of digital mobile communication.)

对数计算源程序，能够在FPGA中计算某数的对数(Determined on the basis of the source, calculated in the FPGA to a certain number of log)
