Energy-efficient reconfiguration of flash-based FPGAs in heterogeneous wireless sensor nodes

Field Programmable Gate Arrays (FPGAs) can be used as hardware-accelerators in Wireless Sensor Networks (WSNs). Their in-field reconfigurability can be utilized for bug fixing and capability enhancements, but the distributed nature of WSNs strongly demands Over-the-air Programming (OTAP) for reconfiguration to avoid manual maintenance at ...More
