Abstract

Soft errors are one of the significant design technology challenges at smaller technology nodes and especially in radiation enviro nments. This paper presents a particular class of approaches to provide reliability against radiation-induced soft errors. The paper provides a review of the lockstep mechanism across different levels of design abstraction: processor design, architectural level, and the software level. This work explores techniques providing modifications in the processor pipeline, techniques allied with FPGA dynamic reconfiguration strategies and different types of spatial redundancy.
