Power and area evaluation of a fault-tolerant network-on-chip
Thawra Kadeed, Eberle A. Rambo, Rolf Ernst · 2017
As fault-tolerant Networks-on-Chip (NoCs) become prevalent in reliable systems, their overhead must be accurately evaluated. In this paper, we evaluate the overhead of a soft error resilient real-time NoC router for ASICs in terms of area and power. We employ a power analysis framework and load profiles that provide accurate power figures. Furthermore, we analyze the power behavior in normal operation as well as under errors. Experiments show that the employed error detection and retransmission schemes in our NoC contribute low power overhead when compared to previously proposed scheme.
