在国际标准组织开放式系统互联（OSI）参考模型下，以太网是第二层协议。10G以太网使用ＩＥＥＥ（电气与电子工程师学会）802.3以太网介质访问控制协议（ＭＡＣ）、ＩＥＥＥ 802.3以太网帧格式以及ＩＥＥＥ 802.3最小和最大帧尺寸。-In the International Standards Organization Open Systems Interconnect (OSI) reference model, Ethernet is the second-layer protocol. 10G Ethernet using the IEEE (Institute of Electrical and Electronics Engineers) 802.3 Ethernet Media Access Control Protocol (MAC), IEEE 802.3 Ethernet frame format, as well as the minimum and maximum IEEE 802.3 frame size.

四人抢答器，包括主持人清楚按键，抢答后屏蔽其他三人的继续抢答，同时答题时间开始，答题时间三档可调。时间到后蜂鸣器发声，指示灯亮起。

本代码用verilog语言配合sopc和nios实现了串口调试的目的。软件编程用C语言描述，只是比较简单的例子，适合初学者做了解用，本人亲自在EP2C8Q上实践。(The code to use verilog language sopc and nios achieved with serial debugging purposes. Software programming using C language description, but relatively simple example for beginners to do with understanding, I personally EP2C8Q on practice.)

说明：  在FPGA实验操作系统实现ASK,FSK,PSK的调制解调，基带信号由M序列发生器产生，经过AD模块在示波器上进行显示，精油DA模块在同一块实验板上进行解调操作，生成信号控制LED灯的亮灭，并与调制输出信号在示波器上同时展示，并进行对比。基带信号为3MHz。(In the FPGA operating system experiment implementation ASK, FSK, PSK modulation and demodulation of the baseband signal generated by the M sequence generator, through the AD module on the oscilloscope display module, oil DA demodulation operation in the same block experiment board, the signal generation control LED lights off, and the modulated output signal displayed on the oscilloscope at the same time, and compared.)

FPGA的驱动并行接口的DAC程序，效率较高。(FPGA-driven parallel interface of the DAC process more efficient.)

利用SCCB和FPGA实现视频采集的论文，对相关开发人员具有很强的参考价值！ (FPGA implementation using the SCCB and video collection of the papers, the relevant developer has a strong reference value ! )

开发工具是quartus II 7.0以上版本，这是一个verilog语言的分频器设计，个人作业设计，供参考学习(verilog，quartus II 7.0)
