FPGA应用举例，非常适合初学者，高手莫下

HDLC通信协议，FPGA实现，包含源文件和仿真测试文件。(HDLC comunication)

This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM. As of this time, the DDR interface only works up to 120 MHz. At 130, DDR data can be read but not written. NOTE: the test bench cannot be simulated with DDR enabled because the Altera pads do not have the correct delay models. * How to program the flash prom with a FPGA programming file 1. Create a hex file of the programming file with Quartus. 2. Convert it to srecord and adjust the load address: objcopy --adjust-vma=0x800000 output_file.hexout -O srec fpga.srec 3. Program the flash memory using grmon: flash erase 0x800000 0xb00000 flash load fpga.srec-This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM.

fpga的RS485代码,非常容易，适合学习(the code of rs485 in fpga, very easy,suitable for learning)

说明：  rgmii代码编写，实现rgmii接口功能，可进行参考设计(The rgmii code is written to realize the function of rgmii interface, which can be used for reference design)

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.)

光纤发送接收模块，verilog编写，主要用于光纤的发送和接收，波长1310nm(Fiber optic transmitter receiver module, verilog written primarily for transmitting and receiving the optical fiber, wavelength 1310nm)

计算机中每一条机器指令的执行，都离不开程序计数器的正确执行，本程序实现程序计数器。(Computer implementation of each machine instruction, are inseparable from the correct implementation of the program counter, this program achieve the program counter.)
