Abstract

For embedded systems, where neither energy nor reliability can be easily sacrificed, this paper presents an energy efficient soft error protection scheme for register files (RFs). Unlike previous approaches, the proposed method explicitly optimizes for energy efficiency and can exploit the fundamental tradeoff between reliability and energy. While even simple compiler-managed RF protection scheme can be more energy efficient than hardware schemes, this paper formulates and solves further compiler optimization problems to significantly enhance the energy efficiency of RF protection schemes by an additional 30% on average, as demonstrated in our experiments on a number of embedded application benchmarks.
