Simple UART for FPGA is UART (Universal Asynchronous Receiver & Transmitter) controller for serial communication with an FPGA. The UART controller was implemented using VHDL 93 and is applicable to any FPGA. Simple UART for FPGA requires: 1 start bit, 8 data bits, 1 stop bit! The UART controller was simulated and tested in hardware.

说明：  学习VHDL可以用得上，有很多实例，可以对照着自己写一些东西(VHDL can be useful to learn, there are many examples, can be done to write something)

基于XIlinx ISE，用Verilog语言实现3分频电路，适合初学者(Based XIlinx ISE, Verilog language using the frequency dividing circuit 3, suitable for beginners)

说明：  使用vivado和Xilinx开发板实现抢答器，开发板为Xilinx Artix-7(Using vivado and Xilinx development board to achieve the responder, the development board is Xilinx artix-7)

使用verilog作为CPU设计语言实现单数据通路五级流水线的CPU。具有32个通用寄存器、一个程序计数器PC、一个标志寄存器FLAG，一个堆栈寄存器STACK。存储器寻址粒度为字节。数据存储以32位字对准。采用32位定长指令格式，采用Load/Store结构，ALU指令采用三地址格式。支持有符号和无符号整数加、减、乘、除运算，并支持浮点数加、减、乘、除四种运算，支持与、或、异或、非4种逻辑运算，支持逻辑左移、逻辑右移、算术右移、循环右移4种移位运算，支持Load/Store操作，支持地址/立即数加载操作，支持无条件转移和为0转移、非0转移、无符号>转移、无符号<转移、有符号>转移、有符号<转移等条件转移。()

说明：  这是一个带声音的弹球小游戏，通过VGA口显示，通过扩展口JA的 pin4和 pin GND输出声音， BTN3 BTN2 控制挡板左右移动，弹球和挡板都自带动画效果(This is a band sound pinball game, through the VGA port shows that through the expansion of the mouth of the JA and pin4 output pin GND voice, BTN3 BTN2 control baffle around Mobile, pinball and baffle all bring their own animation effects)

测量周期,此程序已经在EP2C板子上成功实现(mesure cycle)

The term web server can refer to either the hardware (the computer) or the software (the computer application) that helps to deliver web content that can be accessed through the Internet.(web server)
