xilinx 开发板程序，LED灯控制程序

数字跑表 该跑表具有启动、复位、暂停、暂停后继续计时等功能 能显示的秒计数时间精确到小数点后第二位，即能显示**.**s 按钮设置防抖-Digital stopwatch in the stopwatch with start, reset, suspend, suspended after the time and other functions can show the seconds counting time accurate to the second place after the decimal point, that can show**.** s Anti-Shake button settings

DDR SDRAM控制器verilog代码及中文说明文档,对DDR开发很有用的哈。-Verilog source code for DDR SDRAM controler design,including guide book in chinese.

用VHDL编写的曼切斯特编解码，适用于以太网上流行的基带传输数字编码。(Manchester encoding and decoding written using VHDL, popular Ethernet baseband transmission of digital coding.)

用于实现fpag-cpu的数据通路源代码。用vhdl编写，包括内存，寄存器组，和alu（简陋的alu，仅包含加法器）三大部分通过手动微指令输入信号，可以往内存写入数据，并加载到寄存器组中，通过alu产生结果，结果保存在一个锁存器中，可以把结果写回寄存器组或者内存。本人在quartus下编写仿真通过。附件中未给出相关工程文件。

说明：  对fpga的学习有一点帮助，属于较为基础的部分(It has a little help to the study of FPGA, which belongs to the more basic part)

只需要FPGA两个通用管脚，就可以实现FPGA与PC机进行以太网通信！！如果你有ALTERA_DE1的开发板，可以直接下再看效果，用其他板子就要重新分配一下管脚，推荐使用电流输出。-Only two general-purpose FPGA pins, you can realize FPGA and Ethernet PC machine! ! If you have ALTERA_DE1 development board, you can look under the direct effect, with other board you will need to reconsider the distribution of pins, recommended the use of current output.

This is counter with T_FF.

FPGA设计软件的绝佳入门书籍，本人珍藏，全部吐血奉献之2，请大家赶紧下！-FPGA design software, an excellent entry-books, I treasure all the blood sacrifice of 2, please hurry under the U.S.!

一个8位CISC结构的精简CPU，2还提供了编译器-an eight streamline the structure of the CISC CPU, the two also provided compiler

HDMI协议的Verilog实现，通过对RGB三个通道分别进行TMDS编码完成，纯原创代码(Verilog implementation of HDMI protocol, through TMDS coding of RGB three channels, pure original code)
