基于卫星通信系统的FPGA程序远程更新

Remote Updating of FPGA Program Based on Satellite Communication System

为了解决卫星通信系统中远端信道终端分布广泛,现场更新程序困难的突出问题,文中提出了一种基于卫星通信系统的FPGA程序远程更新的方案.该方案通过卫星链路将FPGA程序更新到远端信道终端,信道终端内再通过MAC自定义协议实现FPGA程序烧写到对应的调制解调板卡,该方案考虑到卫星资源的紧缺,设计了FPGA模块化更新方式.实验结果表明,基于卫星通信系统的FPGA程序远程更新方式比传统的现场更新方式效率更高.

To address the significant issues of widespread distribution of channel terminals at remote stations in satellite communication systems and the difficulties in on-site program updates,a acheme for remote updating of FPGA programs based on satellite communication systems is proposed.The proposed scheme updates the FPGA program to remote channel terminals through satellite links,and within the channel terminals,utilizes a MAC custom protocol to burn the FPGA program onto the corresponding modulation and demodulation board.Considering the scarcity of satellite resources,a modular update approach for the FPGA is designed.Experimental results demonstrate that the remote update method for FPGA programs based on satellite communication systems is more efficient than traditional on-site update methods.
