Timely Error Detection for Effective Recovery in Light-Lockstep Automotive Systems
2015
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems
Safety-relevant systems in the automotive domain often implement features such as lockstep execution for error detection, and reset and reexecution for error correction. Lightlockstep has already been adopted in some such systems due to its relatively low implementation cost given that it does not require deep changes into non-lockstep hardware. Instead, as only off-core activities (i.e. data/addresses sent) need to be compared across different cores, light-lockstep designs are lowly intrusive.
