本实验教程选用Xilinx公司的产品X9572，与之配套的开发软件为ISE4.1i，可进行原理图的输入和VHDL硬件描述语言的输入，并且可利用Modelsim进

说明：  该资料是用vhdl编写的按键消抖程序，按键消抖在使用按键的数字电路中非常重要，如果不对按键信号进行处理，有可能会出现大量错误的按键信号。文件key_xd.vhd是按键消抖程序，文件key_xd.vwf是仿真波形文件。该程序已经通过仿真测试，并且在电路板上调试通过，效果理想。(The information is written in the key consumer vhdl shaking procedures, key consumer shaking in digital circuits using the buttons is very important, if not key signal processing, there may be a lot of the wrong button signal. File key_xd.vhd is key consumer shake procedure is the simulation waveform file key_xd.vwf file. The program has been tested by simulation and debugging in circuit board by, the results are satisfactory.)

运用quartus 软件模拟的电子琴，实现按键出现不同音调的音乐。(Quartus software simulation using keyboard, keys appear to achieve different tones of music.)

用FPGA实现的VGA接口程序，采用的语言是VHDL硬件描述语言，大家可以参照下看看采用的器件是Altera EP2c35-Using FPGA to achieve the VGA interface program, the language used is VHDL hardware description language, we can see under the light of the devices used are Altera EP2c35

说明：  qpsk的fpga实现，包含调制和解调部分，使用verilog语言(FPGA implementation of QPSK)

基于ALTERA AVALON BUS 的 VGA Controller 设计(ALTERA AVALON BUS VGA Controller )

yuv444 与yuv422相互转换verilog语言(yuv444 to yuv422)

本例源代码文件由用户按照书中的操作步骤自己生成，“Example-2-1Project_Navigator_Demo源代码”目录下为源代码的参考文件。“Example-2-1Project_Navigator_Democounter”目录下为完整的工程，包括源代码文件、综合与实现的结果文件、ISE工程文件等，可以使用ISE工程管理器打开工程，供读者参考(In this case the source code files by the user in accordance with the steps the book itself is generated, "Example-2-1 Project_Navigator_Demo source" directory as the source code reference document. "Example-2-1 Project_Navigator_Demo counter" directory for a complete project, including source code files, integrated with the realization of the outcome document, ISE project file, etc. You can use ISE Project Manager, open the project for the reader is referred to)

该书介绍了英特尔的80x86CPU和一些串行通信芯片，以及汇编语言。(The book introduces the Intel 80x86CPU and some serial communications chip, and assembly language.)

Xilinx的I2C总线控制器，verilog版本，文档号是XAPP333，可到Xilinx网上查找具体说明，有对应的VHDL版本的-Xilinx
