网卡的IP核，下载即可用，解压到指定目录下就可以了，参照里面的read me.

基于System Generator的图像处理工程,多媒体处理FPGA实现的源码,基于视频的运动检测(System Generator based image processing engineering, multimedia processing on FPGA source code, based on video motion detection)

RISC-V 芯片设计规范,很有参考价值，开源芯片设计必备参考资料，希望对大家有帮助。(The RISC-V Foundation is chartered to standardize and promote the open RISC-V instruction set architecture)

说明：  在FPGA板卡上面，通过单个按键实现串口的发送功能，带仿真需要自行修改一下工程配置(On the FPGA board, the sending function of the serial port is realized by a single key, and the engineering configuration needs to be modified by the simulation)

802.3an ldpc码编码、译码设计，使用VERILOG hdl语言编写，包括测试代码，(802.3an ldpc code encoding, decoding the design, use of language VERILOG hdl, including test code,)

说明：  五阶CIC梳状积分滤波器，可以综合，非常有参考价值(Fifth-order CIC points comb filter, can be integrated and very useful)

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