说明：  实现电子密码锁的各项功能,经过编译和仿真(Electronic code lock of the function, the compiler and simulation)

这是一个nios工程，控制TFT液晶屏的程序。FPGA平台用Verilog HDL语言编写的，MCU软核程序有C语言编写。通过这一个完成的工程，你就会明白SOPC的一些实现方法。(This is a nios engineering, control TFT LCD screen program. The FPGA platform Verilog HDL language preparation with the nuclear program has a soft, MCU written in C language. Through this a complete project, you will understand some of the SOPC methods of realization. )

基于EDA技术中的对LED扫描电路的实验，程序能成功运行，能直接在开发板上看实验结果(EDA-based LED technology to scan the experimental circuit, the program can run successfully, can see directly in the development of on-board results)

Aurora 8B/10B协议是Xilinx公司针对高速传输开发的一种可裁剪的轻量级链路层协议，通过一条或多条串行链路实现两设备间的数据传输。协议Aurora协议可以支持流和帧两种数据传输模式，以及全双工、单工等数据通信方式。(The Aurora 8B / 10B protocol is a tailor-made lightweight link layer protocol developed by Xilinx for high-speed transmission that enables data transfer between two devices over one or more serial links. Protocol Aurora protocol can support two data transfer modes, stream and frame, as well as full-duplex, simplex and other data communications.)
