Decreasing FIT with diverse triple modular redundancy in SRAM-based FPGAs
2014 IEEE International Symposium on Defect and Fault Tolerance in …, 2014•ieeexplore.ieee.org
This paper explores the concept of Design Diversity Redundancy applied to SRAM-based
FPGAs as a proposal to decrease failure rate. A 32-bit RISC processor MIPS was protected
by coarse grain Triple Modular Redundancy (TMR) and by Diverse TMR (DTMR).
Experimental results under neutron flux radiation show that DTMR can reduce in 40% the
Failure in Time (FIT) of a system when compared to the standard MIPS while the coarse gain
TMR could reduce the FIT in only 10%.
