Abstract :
The Svalinn framework provides comprehensive analysis of multibit error protection overheads to facilitate better architecture-level design choices. supported protection techniques include hardening, parity, error-correcting code, parity prediction, residue codes, and spatial and temporal redundancy. The overheads of these are characterized via synthesis and, as a case study, presented here in the context of a simple openrisc core.
