| 英文摘要: |
| On board processing (OBP) satellite systems have obtained more and more attentions in recent years because of their high efficiency and performance. However, the OBP transponders are very sensitive to the high energy particles in the space radiation environments. Single event upset (SEU) is one of the major radiation effects, which influences the satellite reliability greatly. Triple modular redundancy (TMR) is a classic and efficient method to mask SEUs. However, TMR uses three identical modules and a comparison logic, the circuit size becomes unacceptable, especially in the resource limited environments such as OBP systems. Considering that, a new SEU-tolerant method based on residue code and high-level synthesis (HLS) is proposed, and the new method is applied to FIR filters, which are typical structures in the OBP systems. The simulation results show that, for an applicable HLS scheduling scheme, area reduction can be reduced by 48.26% compared to TMR, while fault missing rate is 0.15%. |
