这是一个关于LCD的VHDL代码的例子

RS232接收程序 无奇偶校验位 并行输出8位数据与data_ready数据准备好信号(RS232 receive procedures without parity 8-bit parallel output data and data ready signal data_ready)

通过vga通讯控制显示器显示七彩条文，通过quartus编译的程序，可用-Communication and Control through the vga display colorful provisions quartus compiled through the procedures that can be used

IC的设计可以分为两个部分，分别为：前端设计（也称逻辑设计）和后端设计（也称物理设计），这两个部分并没有统一严格的界限，凡涉及到与工艺有关的设计可称为后端设计。(The design of IC can be divided into two parts: front-end design (also called logic design) and back-end design (also known as physical design). These two parts do not have a uniform and strict boundary, and the design related to process can be called back-end design.)

设计一个可容纳四组参赛的数字式抢答器，每组设一个按钮供抢答使用。抢答器具有第一信号鉴别和锁存功能，使除第一抢答者外的按钮不起作用；设置一个主持人“复位”按钮，主持人复位后，开始抢答，第一答对一次加1分，答错一次减1分

FPGA实现四位数与四位数乘法，有仿真波形，合理利用FPGA资源(Four-digit and four-digit multiplication is realized by using FPGA. It has simulation waveform and makes rational use of the resources of the FPGA.)

基于Xilinx fpga的ddr2 控制器设计方法-Xilinx fpga-based controller design method of ddr2

LDPC码的短循环对LDPC码性能的影响 (Short Protograph-Based LDPC Codes)

RGB 与YCbCr 颜色空间可以相互转化(RGB and YCbCr color space can be transformed into each other)

实现在屏幕上显示绿色和红色相间的水平条纹。其中，vga_640x480模块将产生行同步信号hsyn和场同步信号 vsync; vga_stripes模块将产生red、green和blue三个输出。(The horizontal stripes of green and red are displayed on the screen. Among them, vga_640x480 module will produce line synchronization signal Hsyn and field synchronization signal vsync; vga_stripes module will produce red, green and blue three outputs.)

Take its complement by applying DeMorgan’s theorem to obtain F in the form of product of complemented products.
