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.

容错 DSP 内核数据通路，对抗 SET 的全方位空间影响

研究界尚未对数字信号处理 (DSP) 内核上的单事件瞬态 (SET) 导致的故障进行彻底研究。此外，随着技术规模的扩大，瞬态故障的影响现在在时间和空间域都变得可见。文献中很少有技术可以同时解决瞬态故障的时间和空间影响。然而，这些方法都没有考虑瞬态故障的全向空间传播。此外，这些方法未能考虑瞬态故障对开关元件的影响。这需要解决瞬态故障对 DSP 内核的时间和全向空间影响的方法。
