As billions of transistors are integrated into one die, researchers have embraced the manycore architecture, posing a challenge to the on-chip communication. In this paper, the authors propose a binary-tree waveguide connected Optical-Network-on-Chip (ONoC) to accelerate the establishment of the lightpath. By broadcasting the control data in the proposed power-efficient binary-tree waveguide, the maximal hops for establishing lightpath is reduced to two. With extensive simulations and analysis, they demonstrate that the proposed ONoC significantly reduces the setup time, and then the packet latency.
