Efficient hardware checkpointing: concepts, overhead analysis, and implementation

  title={Efficient hardware checkpointing: concepts, overhead analysis, and implementation},
  author={Dirk Koch and Christian Haubelt and J{\"u}rgen Teich},
Progress in reconfigurable hardware technology allows the implementation of complete SoCs in today's FPGAs. In the context design for reliability, software checkpointing is an effective methodology to cope with faults. In this paper, we systematically extend the concept of checkpointing known from software systems to hardware tasks running on reconfigurable devices. We will classify different mechanisms for hardware checkpointing and present formulas for estimating the hardware overhead… CONTINUE READING
