NIOSII I2C接口模块及驱动程序，并含有测试程序。对想开发NIOS的工程师很有帮助-NIOSII I2C interface module and driver, and contains the test procedures. NIOS of engineers want to develop useful

Spartan 3 Digilent Demo:This demo drives the perphrials on the Spartan 3 board. This drives a simple pattern to the VGA port, connects the switches to the LEDs, buttons to each anode of the seven segment decoder. The seven segment decoder has a simple counter running on it, and when SW0 is in the up position the seven segment decoder will display scan codes from the PS2 port. This demo how ever does not drive the RS-232 port or the memory. This is a simple design done entirely VHDL not microblaze.

VHDL实现了IIS接口程序，在Quartus II 6.0上编译通过，在板子上可以读取IIS数据-IIS VHDL interface procedures, the Quartus II 6.0 compiled by the board can read data IIS

介绍如何使用vivado来调用和封装IP核，测试AXI4总线的三种功能协议。(It describes how to use vivado to call and package IP core test three functions AXI4 bus protocol.)

本代码绝对真实可靠，VHDL语言写的FPGA呼吸灯。大家可以参考学习，对于VHDL入门还是很有帮助的。库 ieee ； 使用 ieee.std_logic_1164.all ； 使用 ieee.std_logic_arith.all ； 使用 ieee.std_logic_unsigned.all ；已通过编译，已实现呼吸灯功能。 

基于fpga的位同步信号提取仿真 使用vhdl语言 quartus(To use vhdl language quartus fpga bit synchronization signal extraction-based simulation)

8位相 加乘法器，具有高速，占用资源较少的优点-eight multiplier phase together with high-speed, taking up less resources advantages

说明：  Verilog 黄金参考指南是 Verilog 硬件描述语言及其语法 语义 合并以及将它应用到硬件设计的一个简明的快速参考指南。(Verilog Golden Reference Guide is a concise and fast reference guide for Verilog Hardware Description Language and its syntax and semantics merging and its application to hardware design.)

说明：  一个8位RiSC单片机的VHDL代码， 具有很好的参考价值。(an eight RiSC SCM VHDL code, is a good reference value.)
