说明：  Verilog学习文档，介绍基本知识点，语言要素(for learning Verilog)

基于sopc的lcd时钟，开发工具为nios ii和quartus ii9.0(Based on sopc the lcd clock, development tools for the nios ii and quartus ii9.0)

open cores 提供的i2c控制IP核 可直接在FPGA上使用。并带有相关的测试程序(endorsed by the i2c controller IP provided by the open cores on the FPGA. With the relevant test procedures)

library ieee; use ieee.std_logic_1164.all; use ieee.std_logic_unsigned.all; entity song is    port(clk_4MHz,clk_4Hz:in std_logic;      ----预置计数器和乐谱产生器的时钟         digit:buffer std_logic_vector(6 downto 0);  ----高、中、低音数码管指示         zero:out std_logic_vector(4 downto 0);     ----用于数码管高位置低

i2c配置SAA7113，非常有用的程序，做视频采集类必看(i2c configure SAA7113)

说明：  对fpga的学习有一点帮助，属于较为基础的部分(It has a little help to the study of FPGA, which belongs to the more basic part)

基于脉动结构的有限域乘法器，verilog代码(Based on the pulse of the structure of finite field multipliers, verilog code)

用fpga芯片使用vhdl语言对AD转换芯片ADC0809进行控制(Using the fpga chip use language of VHDL AD transform chip ADC0809 control)
