Cross-Layer Dependability for Runtime Reconfigurable Architectures

FPGA-based reconfigurable computing combines the efficiency of hardware with the flexibility of software and is becoming competitive against conventional processor architectures. However, at advanced technology nodes, FPGAs are facing various dependability threats. By exploiting the flexibility that is inherent in reconfigurable architectures, this work presents a comprehensive solution for fault discovery, fault tolerance and aging mitigation, defending against both permanent and transient faults.
