上下LED计数器

说明：  SDRAM硬件控制,fpga的verilog语言，适合学习(SDRAM hardware control, Verilog language of FPGA, suitable for learning)

说明：  一个简单的千兆以太网UDP协议的实现,可以实现数据的收发和ARP，实现PC端与FPGA的以太网通信(A simple implementation of Gigabit Ethernet UDP protocol can realize data sending and receiving and ARP, and realize Ethernet communication between PC and FPGA.)

UART功能,可以增加在NIOS2內,主要來做外部Flash的擦除及寫入,需搭配上位機傳輸字串來控制(UART function, can increase the NIOS2, the main external Flash to do the erase and write, to be a string with the host computer to control the transmission)

一个简单的23计数器，用VHDL实现，可供初学者学习。(A simple 23 counters, with the VHDL implementation, available for beginners.)

I2C总线芯片AT24C02程序设计 C++编程(I2C bus AT24C02 chip program design)

这代码是 I2C 子设备。给定的 I2C 设备是异步的可以用来通电，数字逻辑的其余部分。也可以用作 SMBus 设备。

说明：  按键消抖,避免按键抖动造成信号误触发，增大按键输入的可靠性(Key jitter elimination, avoid key jitter caused by signal error trigger, increase the reliability of key input)

忆阻器的SPICE建模模型说明及仿真结果说明(Memristor SPICE modeling and simulation results show that the model describes)

调整iq幅度不平衡的模块，可以解决载漏和边带问题。(Iq amplitude imbalance adjustment module can be resolved carrier and sideband leakage problems.)
