Survey of Software-Implemented Soft Error Protection

As soft errors are important design concerns in embedded systems, several schemes have been presented to protect systems against them. Embedded can be protected by hardware redundancy; however, hardware-based protections cannot provide flexible protection due hardware-only modifications. Further, they incur significant overheads terms of area, performance, and power consumption. Therefore, redundancy techniques not appropriate for resource-constrained systems. On the other hand, software-based an attractive alternative especially specific-purpose architectures. This manuscript categorizes compares general-purpose processors, such as VLIW (Very Long Instruction Word) CGRA (Coarse-Grained Reconfigurable Architectures).
