Many of these systems are battery powered, and hen e battery lifetime is a riti al design issue. Also these systems, need to meet the timing onstraints imposed by their appli ation domain. An in reasing number of appli ation areas for real-time embedded systems, su h as spa e and onsumer appli ations, have hard onstraints both in terms of en-ergy and reliability. To address these two simultaneously is hallenging be ause lowering the voltage to redu e power onsumption, whi h is the most ommon approa h, has been shown to exponentially in rease the number of transient faults. Moreover, time-redundan y based fault-toleran e te hniques, su h as re-exe ution, and voltage s aling-based low-power te hniques are both relying o
