This paper presents a computer architecture with the ability to respond to radiation-induced faults. The architecture presented advances the state-of-the-art by implementing a redundant multiprocessor system on a commercial-off-the-shelf field programmable gate array. The system, called RadPC, can respond to radiation-induced faults and undergo repairs as necessary. A reliability analysis is conducted using Markov chain models to characterize the architecture’s ability to continue performance despite faults. Further analysis regarding expected radiation exposure is provided for runtime context of the architecture.

RadPC：用于基于现场可编程门阵列的空间计算的新型单事件扰动缓解策略

本文提出了一种具有响应辐射引起的故障的能力的计算机体系结构。提出的体系结构通过在现成的商用现场可编程门阵列上实现冗余多处理器系统来改进最新技术。该系统称为RadPC，可以响应由辐射引起的故障并根据需要进行维修。使用马尔可夫链模型进行可靠性分析，以表征架构在出现故障时仍可继续运行的能力。针对架构的运行时上下文提供了有关预期辐射暴露的进一步分析。
