Abstract: A reliability-aware energy optimization algorithm is proposed for Network-on-Chip (NoC) with voltage scalable links. Considering the effect of reduced voltage on fault rates, this approach achieves energy/reliability trade-off when performing routing path allocation and links voltage assignment statically. A novel energy-efficiency gradient driven heuristic is proposed to assign the voltages for the links during global design space exploration of routing path allocation. Experimental results show that the presented method can efficiently guarantee the communication reliability and bandwidth constraints, without significant loss of energy savings.
