该程序用vhdl编写的vga显示的小游戏，到时屏幕上会显示一个小球，一根棒子，一面墙，棒子可以通过按键控制来移动。而小球在不停的运动，遇到墙会反弹。(Game written by the program with VHDL VGA display, the screen will display a small ball, a stick, a wall, stick to move through the key control. Ball in constant motion, encountered the wall will bounce.)

FPGA MIPS架构CPU，五段流水线功能，ISE开发，verilog语言，可综合，模拟结果正确，内含设计报告(FPGA MIPS CPU, simple five-stage pipeline function, developed by ISE, using verilog language)

速度表（velocity）要求：1．显示汽车Km/h数；2．车轮每转一圈，有一传感脉冲；每个脉冲代表1m的距离；3．采样周期设为10s； 4．要求显示到小数点后边两位；5．用数码管显示；6. 最高时速小于300Km/h。（约为83.3m/s） (use verilog to realize velocity)

这是一个VHDL项目，用于在VIRTEX-4 xc4vsx35 FPGA板中执行接收信号的14位ADC。

数字下变频（DDC）在如今基于软件无线电的架构中对系统的整体性能决定性的影响，代码为基于Matlab的4通道DDC程序，程序中可以根据需要调节滤波器等参数评估DDC的性能对于使用FPGA实现DDC有较大的参考价值(Digital down conversion (DDC) in today' s architecture based on software radio system a decisive impact on the overall performance of the code for the 4-channel DDC Matlab-based program, the program can be adjusted according to filter parameters such as the use of performance assessment FPGA DDC DDC has achieved great reference value)

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.)

实现基于matlab的QMFB的完全重建，是一篇经过仿真且经过测试的正确的代码，可用价值比较高。(Based on matlab QMFB the completely rebuilt, is a through simulation and tested the correct code, can be relatively high value.)
