This paper proposes a new technique to detect and eliminates temporary faults on FPGA systems. Soft core processors which can alleviate radiation induced failures is implemented on Virtex-5 FPGA’s. This Fault tolerant technique is implemented using TMR .It recovers from configuration upsets through partial reconfiguration combined with roll-forward recovery .The lockstep scheme used here eliminates configuration upsets without interrupting normal functioning. Main Significance includes less…

On providing scalable self-healing adaptive fault-tolerance to RTR SoCs
TLDR
The presented system demonstrates the feasibility of the Upset-Fault-Observer concept, which provides a run-time self-test and recovery strategy that delivers fault-tolerance over functions accelerated in RTR cores, at the same time reducing the redundancy scalability cost by running periodic reconfigurable TMR scan-cycles.
The upset-fault-observer: A concept for self-healing adaptive fault tolerance
TLDR
The upset-fault-observer (UFO), an innovative run-time self-test and recovery strategy that delivers FT on request over several function cores but saves the redundancy scalability cost by running periodic reconfigurable TMR scan-cycles, and an adaptive software organization model to manage the proposed FT strategies.
