A framework for low power synthesis of interconnection networks-on-chip with multiple voltage islands
The problem of VI-aware Network-on-Chip (NoC) design is extremely challenging, especially with the increasing core counts in today's power-hungry Chip Multiprocessors (CMPs). In this paper, we propose a novel framework for automating the synthesis of regular NoCs with VIs, to satisfy application performance constraints while minimizing chip power dissipation. Our proposed framework uses a set of novel algorithms and heuristics to generate solutions that reduce network traffic by up to 62%, communication power by up to 32%, and total chip power dissipation by up to 13%, compared to the best known prior work that also solves the same problem.
