Abstract

Fault due to the single-event transient (SET) on digital signal processing (DSP) cores has not been thoroughly studied in the research community. Moreover, as the technology scaling becomes more intense, the impact of transient fault now becomes visible both in temporal and spatial domains. Few techniques have been presented in the literature that simultaneously address temporal and the spatial effects of transient fault. However, none of these approaches consider the omnidirectional spatial propagation of transient fault. Furthermore, these approaches have failed to consider the impact of transient fault on switching elements. This calls for methodology to tackle both the temporal and omnidirectional spatial effects of the transient fault on DSP cores. The proposed approach tackles these issues and presents a novel methodology to generate a low-cost fault-tolerant DSP core datapath against temporal (kc-cycle) and omnidirectional spatial (km-unit) impacts of SET.

抗SET全向空间影响的DSP核心数据容错路径

数字信号处理(DSP)核心的单事件暂态(SET)故障在学术界还没有得到深入的研究。此外，随着技术尺度化程度的提高，暂态故障的影响在时间和空间上都变得清晰可见。文献中提出的同时处理暂态故障的时间和空间影响的技术很少。然而，这些方法都没有考虑瞬态故障的全向空间传播。此外，这些方法没有考虑暂态故障对开关元件的影响。这就需要一种方法来解决暂态故障对DSP核的时间和全方位的空间影响。所提出的方法解决了这些问题，并提出了一种新的方法来生成低成本的容错DSP核心数据路径，以对抗SET的时间(kc-cycle)和全向空间(km-unit)影响。
