Photonic Networks-on-Chip (NoCs) have become a promising route to interconnect processor cores on chip multiprocessors (CMP) in a power efficient way. Although several photonic NoC proposals exist, their use is limited to the communication of large data messages due to a relatively long set-up time for the photonic channels. In this work, we evaluate a reconfigurable photonic NoC in which the topology is adapted automatically to the evolving traffic situation. This way, long photonic channel set-up times can be tolerated which makes our approach more compatible in the context of shared-memory CMPs.
