A Novel Laser Source Supply Scheme for Optical Network on Chip

Abstract

With the increasing number of integrated processor cores on a single chip, the bandwidth, speed, and power consumption of electrical interconnect cannot meet the needs of researchers. As a new technology, optical interconnect has become an alternative scheme for electrical interconnection. However, the traditional supply strategy of laser power brings a lot of static power loss, which will become a factor that cannot be ignored in the development of optical interconnect. In this paper, we propose a dynamic laser source supply scheme based on the autoregressive integrated moving average model, which can reasonably adjust the laser source size by prediction. The simulation results show that our dynamic supply scheme can save more than 70% of the laser power compared with the static supply under the real application of the PARSEC flow benchmarks.
