PCIe数据链路层的协议详解，对做PCIe接口有非常重要的指导价值。(PCIe data link layer protocol detailed, do PCIe interface very important value.)

说明：  KMP算法的Verilog HDL实现，模式串从模块的外部输入，计算next函数，然后进行KMP匹配。有仿真。环境为Quartus II 8.0 Web Edition。(Verilog HDL implementation KMP algorithm, pattern string from the module' s external input, calculate next function, then KMP matching. A simulation. Environment for the Quartus II 8.0 Web Edition.)

我用VHDL写的正弦，用FPGA内部ROM，有仿真testbench,在quartus里可以运行。在板子里已经验证-I used to write VHDL sinusoidal, using FPGA internal ROM, has simulation testbench, you can run in Quartus. Yard has already been verified in the plates

原创：cos函数和sin函数的VHDL实现，很实用(cos of the VHDL implementation)

how to use step motor control

利用VHDL语言编写的一个crc功能模块，可下载到FPGA实现功能-use VHDL to prepare a crc function of the module, which can be downloaded to the FPGA functions

用FPGA模拟VGA时序、模拟PS/2总线的键盘接口VHDL源代码，基于Xilinx spartan3-VGA FPGA timing simulation, simulation PS/2 keyboard interface bus VHDL source code, Based on Xilinx spartan3

这是一个在FPGA上实现CRC算法的程序，包含了CRC-8,CRC-12,CRC-16,CRC-CCIT,CRC-32一共五种校验形式。-err

vga编程。实现3种模式的vga控制，分别产生横彩条，竖彩条，棋格彩条的显示-vga programming. Realization of the three-mode vga control, generate horizontal color of the color of the shaft, and the chess grid color of the show

FPGA AD采集八路数据，12位分辨率，小梅哥FPGA的开发程序，实测可用(FPGA AD collects eight path data, 12 bit resolution, and the development program of Mayo FPGA.)
