图像降噪GUI界面，用到butterworth滤波器，中值滤波器和维纳滤波器，仅供参考。(noise reduction using media filter )

这是VHDL中计数器的代码。

说明：  一个使用VHDL进行正弦波信号产生的历程，非常有用。(A sine wave signal generator using VHDL for the course, very useful.)

This tutorial explains how to communicate with IO devices on the DE2 Board and how to deal with interrupts using C and the Altera Monitor Program. Two example programs are given that diplay the state of the toggle switches on the red LEDs. The fi rst program uses the programmed I/O approach and the second program uses interrupts.-This tutorial explains how to communicate with IO devices on the DE2 Board and how to deal with interrupts using C and the Altera Monitor Program.

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)

基于FPGA的希尔伯特变化的verilog代码(Hilbert change verilog code)

MBD-FPGA数字滤波器设计基本流程,基于DSP builder(MBD-FPGA basic process of digital filter design)

SHIFT_8REG是8位的一个具有移位功能的寄存器，每一次数据打入都会从这个寄存器的最低位打入，并相应进行向左移位。 ODD_110BREG是一个3位的备份寄存器，寄存器中存放的是奇数帧的同步头，也就是110。 EVEN_9BHREG是一个8位的备份寄存器，寄存器中存放的是偶数帧的同步头，也就是10011011。这两个寄存器的初始值在系统一开始就打入。 -SHIFT_8REG is eight with a displacement of the functional Register, Each will enter the data from the register into the lowest point, and the left shift accordingly. ODD_110BREG is a three backup Register, the Register is stored in the odd frame synchronization head, is 110. EVEN_9BHREG 8 is a backup Register, which register is kept even the first frame synchronization, is 10011011. This register the two initial value of the system into a start.

很好的quartus软件仿真教程，flash版。-Good quartus software simulation tutorials, flash version.

轴系测试程序，多通道输入输出，实现时域、频域、轴心轨迹、瀑布图等功能。(Shafting test program, multi-channel input and output, to achieve time domain, frequency domain, orbit, waterfall and other functions.)
