Abstract

Circuits related to nuclear facilities and on-orbit circuits typically require fault-tolerant reinforcement to cope with harsh radiation environments. While the traditional fully Triple Modular Redundancy (TMR) method can effectively reinforce circuits, it suffers from the problems of large circuit area and high power consumption. To solve this problem, this paper proposes a Partial TMR method based on the HITS algorithm (Hyperlink-Induced Topic Search), which can effectively perform circuit fault tolerance. This method sorts the importance of triggers in the circuit based on the HITS algorithm and uses the Fault Interval Time (MTBF) of the Bi-Logic Cone model as the judgment criterion to determine the number of triggers that need to be redundantly designed under partial TMR. Some commonly used modules of an on-orbit processor were tested to verify the effectiveness of the proposed redundancy method in this paper. The experimental results show that the resource overhead can be reduced by at least 20% while achieving an MTBF of 99.9% under TMR.
