现场可编程门阵列（FPGA）已经被证明通过允许电路被定制到任何感兴趣的应用而为许多计算应用提供高计算密度和效率。FPGA还支持可编程性，允许电路在以后通过重新配置进行更改。人们对在空间和其他辐射环境中利用这些好处很感兴趣。然而，FPGA对辐射非常敏感，必须非常小心才能正确解决基于FPGA的系统中辐射的影响。本文将重点介绍辐射对基于FPGA的系统的影响，并总结在此类环境中部署FPGA所面临的挑战。将描述几种众所周知的缓解方法，并讨论FPGA定制系统以提高可靠性的独特能力。最后，将介绍两个案例研究，总结在辐射环境中成功部署FPGA。
Field-programmable gate arrays (FPGAs) have been shown to provide high computational density and efficiency for many computing applications by allowing circuits to be customized to any application of interest. FPGAs also support programmability by allowing the circuit to be changed at a later time through reconfiguration. There is great interest in exploiting these benefits in space and other radiation environments. FPGAs, however, are very sensitive to radiation and great care must be taken to properly address the effects of radiation in FPGA-based systems. This paper will highlight the effects of radiation on FPGA-based systems and summarize the challenges in deploying FPGAs in such environments. Several well-known mitigation methods will be described and the unique ability of FPGAs to customize the system for improved reliability will be discussed. Finally, two case studies summarizing successful deployment of FPGAs in radiation environments will be presented.
