异步fifo_MSB

在FPGA开发板上用VHDL语言实现了贪吃蛇游戏，开发软件为quartus 2.这是详细的实验报告，包括源码(Snake game with VHDL FPGA development board, software development quartus 2 This is a detailed experimental report, including the source)

This is a simple verilog code for stopwatch undre xlinx ISE webpack based for NEXYS3 board.

基于vhdl的pid控制器设计，可以用quartus等软件实现。数字控制系统pid设计源代码。(Pid controller based on VHDL design, can use the quartus software implementation, etc. Digital pid control system design of source co)

8086微机原理实验：8251串行接口、8253计数器、数码管、跑马灯。汇编语言。(8086 microcomputer principle experiment: 8251 serial interface, the 8253 counter, digital tube, Marquee. Assembly language.)

说明：  使用FPGA实现sobel边缘检测的图像处理算法，更改后可直接使用在自己的系统上。(FPGA is used to implement the image processing algorithm of Sobel edge detection, which can be directly used in its own system after change.)
