SoC-Wishbone System IP核的VHDL语言源代码，需要的开发环境是QUARTUS II 6.0。(SoC-Wishbone System IP core VHDL language source code, the need for the development environment is QUARTUS II 6.0.)

此为数学形态滤波器消燥的代码，用于一维信号，涉及一个具体的例子，需要的话可以自己修改，修改相应的结构元素。(This is a mathematical morphology filter away dry code, used to one dimensional signal, involving a concrete example, necessary can change ourselves, change the structure of the corresponding elements)

用Verilog HDL实现I2C总线功能，对I2C总线有很大帮助-I2C bus contrll functions implemented by Verilog HDL.

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.
