Fault Tolerance Technique for Dynamically Reconfigurable Processor

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 time overhead and reduced hardware usage. Fault injection Experiments are used for the validation process.
