this is a Multiplier and Accumulate (MAC). written in VHDL

七段LED数码管显示译码器设计，将输入的16位二进制数据分别输出到4个数码管上(Seven-segment LED display decoder design, the input of 16 binary data are output to the four digital tube)

这是个UART发送的VHDL程序，调试过，还可以-This is a UART to send the VHDL program, debug, and can also be

基于Xilinx FPGA实现PS2键盘鼠标接口。版本1.0-Based on Xilinx FPGA realize PS2 keyboard and mouse interface. Version 1.0

自编的64B/66B解码程序，做毕业设计的时候写的。(The decoding process 64B/66B , written when i am in the school。)

高级verilog编程实现讲义，全英文讲义 -Senior verilog programming lecture notes, handouts in English

eDP接口TFT-LCD显示驱动原码（verilog+c）(eDP Interface TFT-LCD display driver source code (verilog+c))

此为数字逻辑书上的答案，应该很多同学都需要吧，关于数字逻辑(This is the answer books, digital logic, it should be a lot of students need it, on the digital logic)

这是本人自己编写的可用于256*256大小的图像进行sobel边缘检测的vhd文件，可在QuartusII或MaxplisII下综合和仿真，并在FPGA上测试过。可以进行修改支持其他大小图像的sobel边缘检测，同时还可以实现其它的图像模块化处理算法，例如高斯滤波，平滑等。(this is my own preparation for the 256* 256 size of the image segmentation Edge Detection vhd document in the next QuartusII or MaxplisII integrated and simulation, and the FPGA tested. Can be adapted to support other size image segmentation edge detection, It can also achieve other modular image processing algorithms, such as Gaussian filtering, smoothing and so on.)
