With an increasing number of processing elements being integrated on a single die, Network-on-Chips (NoCs) are emerging as a significant contributor to overall chip power consumption. While some solutions have been proposed to reduce this power consumption, none of them can be applied to Spatial Division Multiplexing (SDM)-based NoCs. In this paper, the authors introduce a method to minimize the power consumption of an SDM-based NoC by frequency minimization, while still satisfying the bandwidth requirements. The problem is integrated with the connection-routing problem which is modeled as a Mixed-Integer Quadratic Constrained Problem (MIQCP).
