An adaptive cross-layer fault recovery solution for reconfigurable SoCs

Due to the technology scaling, the reconfigurable SoCs built on SRAM-based FPGAs become more susceptible to radiation and aging effects. This paper proposes an adaptive cross-layer fault recovery solution based on hardware/software co-design for reconfigurable SoCs. By pyramidal structure design and cross-layer adaptivity, our solution gives both consideration to hardware circuit integrity at the hardware level and application operating normality at the software level with reduced correction cost. The experiment result shows that the proposed solution can efficiently increase the system reliability and decrease the correction cost.
