Abstract

FPGAs are applicable to implementation of fault tolerant systems due to their reconfigurability. Such fault tolerant systems can be classified according to recovering methods: fail-soft and standby-redundant systems. In this work, we propose a probabilistic model for both FPGA-based fault tolerant systems, and analyze the reliability and performance of the systems. Analytical results show that there exists an appropriate choice of the implementation of fault tolerance with FPGAs between the two systems for the specification required for its application.
