Networks-on-chip (NoCs) are key components in many-core chip designs. Dynamic power-awareness is a new challenge present in NoCs that must be efficiently handled by the routing functionality as it introduces irregularities in the commonly used 2-D meshes. In this article, we propose a logic-based routing algorithm, iFDOR, oriented towards dynamic powering down one region within every application partition on the chip through dynamic rerouting, with low implementation costs. Results show that we can successfully shutdown an arbitrary rectangular region within an application partition without significant impact on network performance.
