  text: Dynamic thread duplication is a known redundancy technique for multi-cores.
    The approach duplicates a thread under observation for some time period and compares
    the signatures of the two threads to detect errors. Hybrid multi-cores, typically
    implemented on platform FPGAs, enable the unique option of running the thread
    under observation and its copy in different modalities, i.e., software and hardware.
    We denote our dynamic redundancy technique on hybrid multi-cores as thread shadowing.
    In this paper we present the concept of thread shadowing and an implementation
    on a multi-threaded hybrid multi-core architecture. We report on experiments with
    a block-processing application and demonstrate the overheads, detection latencies
    and coverage for a range of thread shadowing modes. The results show that trans-modal
    thread shadowing, although bearing long detection latencies, offers attractive
    coverage at a low overhead.
