SafeDE

SafeDE (Safe Diversity Enforcer) is hardware module provides light-lockstep support by means of a non-intrusive and flexible hardware module that preserves staggering across cores running redundant threads, thus bringing time diversity to avoid common cause failures.

In contrast to the traditional lockstep solution, in the light-lockstep approach there are two independent cores that can execute either critical tasks or non-critical tasks independently.
