改自特权同学verilog语言写sdram测试程序；支持256M内存(verilog sdram )

模块vedic_2_x_2（A，B，C  ；）；

   基于fpga开发板的按键去抖verilog代码实现

这是网上找到的一篇关于SDRAM 驱动的程序，注解非常详细，并且很有条理。但因为很久的程序了，所以忘记了出处，印象中是特权同学的。

说明：  VC707_MIG_DDR3.sim文件夹中是仿真的文件：testbench和DDR3模型参数 VC707_MIG_DDR3.srcs文件夹中是源文件，包含DDR3的控制、收发模块、顶层文件(VC707_ MIG_ In ddr3.sim folder are simulation files: testbench and DDR3 model parameters VC707_ MIG_ Ddr3.srcs folder is the source file, including DDR3 control, transceiver module, top-level file)

Construction and Experimental Evaluations of User-Centered Power

WM8731芯片的音效处理verilog代码， WM8731芯片是音频ADCDAC芯片(WM8731 audio processing chip verilog code, WM8731 chip audio ADC DAC chip)

FPGA／CPLD技术是近年来计算机与电子技术领域的又一场革命。本书以Xilinx与Altera公司的FPGA／CPLD为主，详细介绍了FPGA／CPLD从芯片到MAX+plusⅡ、Quartus与ISE开发环境和Verilog／VHDL语言，并以交通灯逻辑控制、电子钟与点阵LED显示、LCD液晶显示及计算机ISA接口和PCI接口的设计等为例，由浅入深地详述了如何应用FPGA／CPLD进行电子设计。书中的大多数电路图和源程序已经过实例验证，读者可以直接应用于自己的设计。本书的特点是强调实用性和先进性，力求通俗易懂。 本书适用于计算机、电子、控制及信息等相关专业的在校大学生，对广大工程技术人员也具有实用价值。(FPGA/CPLD technology in recent years the field of computer technology and electronic another revolution. Book Xilinx and Altera' s FPGA/CPLD based, detailing the FPGA/CPLD from the chip to MAX+plus Ⅱ, Quartus and ISE development environment and Verilog/VHDL language and logic control traffic lights, electronic bell with dot matrix LED display , LCD liquid crystal display and computer ISA interface and PCI interface design, for example, progressive approach to detail how the application of FPGA/CPLD for electronic designs. Circuit and the source of most of the book have been instances of verification, the reader can be directly applied to their own design. Characteristic of this book is to emphasize the practical and advanced, best straightaway. This book applies to computers, electronics, control and information and other related professional college students, the majority of engineering and technical personnel also has practical value.)

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.)
