BCH编码器和解码器的源代码，FLASH控制器，通信是必要的哦

利用matlab设计了一个切比雪夫滤波器，并且对滤波器性能进行了仿真分析。(Using the matlab design a chebyshev filter, and has carried on the simulation analysis on filter performance. )

VHDL控制VGA 在显示器上显示图形，分辨率800X600，晶振50Mhz-VGA control with VHDL

使用verilog语言，滚动显示“verilog”字符串程序代码及相关说明(Using verilog language, scrolling display " verilog" string code and instructions)

本实例用于SDRAM完成读写功能: 先向SDRAM里面写数据，然后再将数据读出来做比较，如果不匹配就通过LED变亮显示出来，如果一致，LED就不亮。(The examples for SDRAM read and write functions.)

能实现输入0.5 1 5块钱的累加，然后对应购买的商品价格进行比较，显示找的钱数或错误灯(MY English is very good)

DDS在现在运用月来越广泛，在相对带宽、频率转换时间、相位连续性、正交输出、高分辨力以及集成化等方面都远远超过了传统频率合成技术所能达到的水平，为系统提供了优于模拟信号源的性能。利用DDS技术可以很方便地实现多种信号。在FPGA上实现的DDS-DDS now to the use of more extensive relative bandwidth, frequency conversion time, phase continuity, quadrature output, high-resolution and integration, and other aspects far more than the traditional frequency synthesizer technology can achieve the level To provide a superior analog signal source performance. DDS technology can be used very easily to a variety of signal. FPGA Implementation of DDS

说明：  FFT 1024 point, in 10 state

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)

说明：  实现主干道交通灯显示，以状态机程序实现，并用数码管进行红绿灯倒计时的显示，内置计数模块，交通灯控制模块，数码管显示模块，并对各模块用电路图的方式进行连接。对于学习VHDL语言有所帮助。(The main road traffic light display is realized by the state machine program, and the digital tube is used to display the traffic light countdown. The counting module, the traffic light control module and the digital tube display module are built in, and each module is connected by the circuit diagram. It is helpful for learning VHDL.)
