Hynix公司8M Byte SDR SDRAM的Verilog语言仿真实现

实现图像的中值滤波功能，文件里有效果展示(The realization of the median filter function of the image, the file has the effect of display)

针对AD9826驱动设计的Verilog代码，主要是配置ccd采样的设计(The Verilog code is designed for AD9826, to configuration ccd sampling )

关于基数分频技巧设计,基于VHDL语言,对实际设计有帮助-DIVIDE

vhdl source code for 8 bit datapath logic

设计一个可供6组参赛选手使用的抢答器，具体要求如下：1)  可容纳6组参赛者的数字智能抢答器，每组设置一个抢答按钮供抢答者使用；2)  电路具有第一抢答信号的鉴别和锁存功能；3)  设置计分电路4)  设置犯规电路。顶层设计使用图形模块连线搭建，顶层功能模快均使用VHDL语言编写

在数字通信中，通常直接从接收到的数字信号中提取位同步信号，这种直接法按其提取同步信号的方式，大致可分为滤波法和锁相法。锁相法是指利用锁相环来提取位同步信号的方法，本设计方案就是基于锁相环的位同步提取方法，能够比较快速地提取位同步时钟，并且设计简单，方便修改参数。采用Quartus II设计软件对系统进行了仿真试验，并用Altera的Cyclone II系列FPGA芯片Ep2c5予以实现。(In digital communication, usually from receiving directly in digital signal extracted a synchronized signal, the direct method according to the extraction synchronized signal way, can be roughly divided into filtering method and phase lock method. Phase lock method is using of phase locked loop to extract a synchronized signal method, the design scheme is based on phase locked loop of a synchronous extraction method and can be quickly extract a synchronous clock, and design simple, convenient modification parameter. The Quartus II design software of the system, and the simulation test Altera Cyclone II FPGA chip to achieve Ep2c5 series.)

6713emiftofpgatopci,这个是完整的一套从6713的emif到fpga的双口ram，然后主机通过9054到双口ram，交换数据完成-6713emiftofpgatopci, this is a complete set of the EMIF from 6713 to the FPGA

十分基础的CCD的测试程序，大家可以下载调试CCD(this is a ccd test chengxu ,it is very good to use ,you can down it )
