Field Programmable Gate Arrays (FPGAs) are very successful platforms that rely on large configuration memories to store the circuit functions required by users. Faults affecting such memories are a major dependability threat for these devices, and the applicability of FPGAs on critical systems depends on efficient means to mitigate their effects. The main means to effectively remove such faults, namely configuration scrubbing, consists in rewriting the desired contents of this memory and suffers from high power consumption and a long mean time to repair (MTTR). In this work we propose Scrubbing Unit Repositioning for Fast Error Repair (SURFER), a novel approach to exploit partial dynamic reconfiguration coupled with fine-grained redundancy to greatly reduce the MTTR for FPGAs subject to upsets in their configuration memories.

The order Rodentia is the largest order of mammals and is widespread through different habitats (Wilson & Reeder, 2005). Rodents of the family Erethizontidae include New World porcupines and comprises 15 species distributed across three genera: Chaetomys, Coendou and Sphiggurus (Woods & Kilpatrick, 2005). The orange-spined hairy dwarf porcupine (Sphiggurus villosus) is a solitary, nocturnal and arboreal animal, endemic to the Atlantic forest habitat, occurring in southeastern and southern Brazil (Lange & Schmidt, 2014; Oliveira & Bonvicino, 2006). Although occur in primary Atlantic Forest, they may be commonly found on forest borders and, occasionally, near urban areas where human (Jorge et al., 2016) and domestic dogs (Lange & Schmidt, 2014) injuries caused by its spines may occur.Additionally, porcupines are amongst the most frequently roadkilled animals in Brazil (Coelho, Kindel, & Coelho, 2008).Haemotropic mycoplasmas (haemoplasmas) are epicellular bacteria that attach to erythrocyte's surface of a wide range of mammalian hosts (Messick, 2004), including human beings (Hattori et al., 2020).Two haemotropic Mycoplasma species have been reported in
