Researchers deployed an unprotected open-source Tensil neural network accelerator on the Zynq UltraScale+ MPSoC platform to perform ResNet-20 inference tasks. During the experiment, the device was exposed to a cumulative dose of $4.29 \times 10^{10}$ p/cm$^2$ under proton irradiation ranging from 20 to 58 MeV. There were seven workload interruptions: two instances of notebook process restarts, four board resets or reboots, and one power cycle. Two of these failures caused output damage, returning incorrect CIFAR-10 classification results; in one instance, 39 consecutive inputs returned non-pooling categories. Although no abnormalities were detected in kernel logs, memory tests, or sampled power monitoring, the planned reconfiguration ultimately resolved the deadlock issue. All nine failures occurred in the beam area of 4 cm in nominal size (exposing the SoC, LPDDR4, and board-level circuits), and not in the central field of the 2-cm SoC…

Proton Irradiation Characterization of an Open-Source ML Accelerator on a Zynq UltraScale+ MPSoC

研究人员在 Zynq UltraScale+ MPSoC 上部署未防护的开源 Tensil 神经网络加速器,执行 ResNet-20 推理任务,并在 20 至 58 MeV 质子辐照下累计注入 $4.29 \times 10^{10}$ p/cm$^{2}$。实验期间发生七次工作负载中断,导致两次笔记本进程重启、四次板卡重置或重启及一次电源循环;其中两次输出损坏事件返回了错误的 CIFAR-10 分类,最长的一次连续 39 个输入返回了不在池中的类别。尽管内核日志、内存测试和采样功率未显示异常,但通过计划的重配置最终解决了卡死序列问题。所有九次故障均发生在标称 4 cm 的束流下暴露 SoC、LPDDR4 及板级电路时,而未在 2 cm 的 SoC 中心场中发生。该基准数据记录了可用性损失和静默输出损坏现象,…
