ov5620在FPGA中的使用

The description header can be found in signal_processing_library.h.

说明：  通过循环读写DDR3内存，了解其工作原理和DDR3控制器的写法，由于DDR3控制复杂，控制器的编写难度高，这里笔者介绍XILINX的MIG控制器情况下应用，是后续音频、视频等需要用到SDRAM实验的基础。(Through reading and writing DDR3 memory circularly, we can understand its working principle and the writing method of DDR3 controller. Because of the complexity of DDR3 control, it is difficult to write the controller. Here, the author introduces the application of Xilinx's MIG controller, which is the basis of SDRAM experiment for subsequent audio and video.)

In the data management system a significant role of the Data link layer is to convert the unreliable physical link between reader and tag into a reliable link. Therefore, the RFID system employs the Cyclic Redundancy Check (CRC) as an error detection scheme. In addition for reader to communicate with the multiple tags, an anti-collision technique is required. The technique is to coordinate the communication between the reader and the tags. The common deterministic anti-collision techniques are based on the Tree algorithm such as the Binary Tree and the Query Tree algorithms.

说明：  试用Verilog HDL语言，设计十进制计数器，将计数过程用一个数码管进行显示（0～9）。要求首先使用Modelsim软件进行功能仿真，然后使用Quartus软件综合，并下载到开发板进行电路功能测试。(Using Verilog HDL language, a decimal counter is designed. The counting process is displayed by a digital tube (0 ~ 9). It is required to first use Modelsim software for functional simulation, then use quartus software for synthesis, and download to the development board for circuit functional test.)

一个从0-1MHZ的正弦DDS发生器，如果你对Verilog语言以及FPGA有兴趣的话，这个可以作为一个入门的教程。有兴趣的朋友们可以来下载，如果有什么不懂的地方可以随时请教楼主，如果代码中有什么问题的话，也可以向楼主提出改正。

其中两个项目自己做的：一个是雷达模拟跟踪，基于FPGA/CPLD的，里面包含了PCB和VHDL码，还有一个是SDIO的驱动程序（包括PCB原理图，SDIO协议方面的资料还有就是源码，这项目可用），还有一些嵌入式方面的资料，如TCP/IP协议栈的实现，FPGA的一些仿真实例(Two of the projects themselves to do: a tracking radar simulator is based on FPGA/CPLD)

说明：  100个vhdl例子，对初学者很有用，可以用MAX+PLUS 2来编译仿真的(100 vhdl example, useful for beginners, you can use the MAX+ PLUS 2 to compile the simulation)

fpga的按键程序，实现按键和led的对应点亮。(The key program of FPGA realizes the corresponding lighting between keys and led.)

图像去雾算法FPGA实现，使用xilinx Vivado开发环境(Image dehazing algorithm FPGA implementation using xilinx Vivado development environment)

资源描述 利用实验板实现模六十计数，即00—01—02—03—04—…59—00—01…，并在Basys2实验板的AN1~AN0或（LD7~LD0）上显示。 下载配置文件到实验板BASYS2上，观察验证实验现象。  使用verilog语言设计实现---模六十计数器
