利用最新的嵌入式开发工具EDK，在FPGA 中完成对PDIUSBD12 的硬件定制和固件编程，从而在FPGA 中实现U S B 控制器， 并最终完成U S B 的枚举过程、驱动程序的开发和简单的应用。(Using the latest embedded development tools, EDK, in the FPGA completes its PDIUSBD12 custom hardware and firmware programming, in order to realize USB controller in the FPGA, and ultimately complete the USB enumeration process of driver development and simple应用.)

完成GPS的IRIG_B码解码，已经模块化，并且有详细的中文注释(Completed the GPS IRIG_B of decoding modular, and there are detailed notes in Chinese)

实现数字变下频的matlab程序，CIC,HB,FIR滤波器代码都在其中(Realize digital variable frequency under matlab, CIC, HB, FIR filter code in it )

说明：  熟悉IIC协议总线协议，采用IIC总线对图像采集传感器寄存器进行配置，并转换为RGB565格式。 利用异步FIFO完成从摄像头输出端到SDRAM 和SDRAM 到VGA 接口各跨时钟域信号的传输和处理。 利用 SDRAM 接口模块的设计，实现了刷新、读写等操作；为提高SDRAM 的读写带宽，均采用突发连续读写数据方式；并采用乒乓操作实现 CMOS 摄像头与VGA的帧率匹配。 利用双线性插值方法实现对图像640×480到1024×768的放大操作。 完成VGA显示接口设计。(Familiar with IIC protocol bus protocol, IIC bus is used to configure the register of image acquisition sensor and convert it into RGB565 format. Asynchronous FIFO is used to transmit and process signals across clock domain from camera output to SDRAM and SDRAM to VGA interface. With the design of SDRAM interface module, refresh, read and write operations are realized. In order to improve the read and write bandwidth of SDRAM, burst continuous read and write data mode is adopted, and table tennis operation is used to achieve frame rate matching between CMOS camera and VGA. The bilinear interpolation method is used to enlarge the image from 640*480 to 1024*768. Complete the VGA display interface design.)

AD9235FPGA编程 可AD采集信号 信号频谱检测 检测任意波形输入(AD9235FPGA programming allows AD to collect signal and spectrum detection and detect arbitrary waveform input.)

应用背景交通信号灯，自动检测有无行人，根据检测的状态来调节灯的状态，完整VHDL代码外加模拟仿真时序图关键技术 设计一个交通信号灯，有A、B两条路，装置自动检测A路口和B路口是否有人，RST信号能够将交通灯的状态置到A路绿灯亮，B路红灯亮，5秒钟检测一个状态，当A路口有人时，A路绿灯保持，每隔5秒检测一次，当A路口没有人了，绿灯变为黄灯，5S后再变为红灯，同时B路口变为绿灯，再5S后检测B是否有人，有人保持绿灯，没人变为黄灯，再变为红灯，依次进行~~

说明：  利用正点院子开拓者fpga实现DDS功能，实现三角波、正弦波、方波的发生。(Implementation of DDS with FPGA)

FFT程序，此程序虽然耗逻辑资源很大，但是在接受数据后的第7个时钟沿就可以输出FFT变换后的数据，对要求时延较低的系统可以考虑-FFT procedure, this procedure should not consume a lot of logic resources, but the data in the first seven clock can be output along the FFT transformed data, the requirements of time-delay system can be considered lower
