设计并实现了基于UDP的FPGA远程升级系统,包括完整的FPGA工程和整套计算机上位机GUI程序。FPGA运行时,通过有线网络与计算机相连,在计算机上简单地操作上位机GUI程序即可实现FPGA的在线升级烧写、热启动等功能。实际上,在没有网口只有串口的情况下,这套远程升级系统通过模式选择开关可以切换为串口模式,而计算机上位机GUI程序也相应切换为串口模式,通过串口实现FPGA远程升级等功能。

In the paper,the design and implementation of UDP-based FPGA remote upgrade system is designed,including a complete FPGA project and a complete set of host computer GUI program.When the FPGA is running,it is connected to the computer through the wired network,and the host computer GUI program is simply operated on the computer,which can realize the online upgrade and flashing,warm start and other functions of the FPGA.In fact,in the case of no network port and only serial port,this remote upgrade system can be switched to serial port mode through the mode selection switch,and the host computer GUI program is also switched to serial port mode accordingly,and FPGA remote upgrade and other functions are realized through the serial port.
