TY - JOUR A2 - Margala, Martin AU - Anwer, Jahanzeb AU - Meisner, Sebastian AU - Platzner，fpga的辐射容限是一个重要的研究领域，特别是用于航空航天和卫星任务中的电子器件的可靠计算。本研究背后的动机是由于辐射粒子引起的单事件效应，FPGA硬件的可靠性退化。冗余是提高辐射敏感应用容错能力的常用技术。然而，冗余带来了过多的区域消耗、延迟和功耗开销。此外，冗余电路实现的结构和资源使用随冗余插入算法和冗余级数的不同而不同。根据轨道和空间天气条件的不同，任务运行期间的辐射环境也会有所不同。因此，冗余造成的开销也应该在运行时针对当前辐射水平进行优化。在本文中，我们提出了一种动态可靠性管理技术(DRM)，利用辐射数据，解释它，选择一个合适的冗余级别，并执行运行时重构，从而改变目标计算模块的可靠性级别。DRM由两部分组成。 The design-time tool flow of DRM generates a library of various redundant implementations of the circuit with different magnitudes of performance factors. The run-time tool flow, while utilizing the radiation/error-rate data, selects a required redundancy level and reconfigures the computation module with the corresponding redundant implementation. Both parts of DRM have been verified by experimentation on various benchmarks. The most significant finding we have from this experimentation is that the performance can be scaled multiple times by using partial reconfiguration feature of DRM, e.g., 7.7 and 3.7 times better performance results obtained for our data sorter and matrix multiplier case studies compared with static reliability management techniques. Therefore, DRM allows for maintaining a suitable trade-off between computation reliability and performance overhead during run-time of an application.
