SUMMARY:An Approximate Thermal-Aware Q-Routing for Optical NoCs
DESCRIPTION:Workshop\n\nAn Approximate Thermal-Aware Q-Routing for Optical
  NoCs\n\nYe\n\nOptical networks-on-chips (NoCs) based on silicon photonics
  have been proposed as an emerging communication architecture for many-cor
 e chip multiprocessors. However, one of the key challenges is the thermal 
 sensitivity of silicon photonic devices under on-chip temperature variatio
 ns, which would result in significant thermal-induced optical power loss i
 n optical NoCs. In this work, we propose an approximate Q-routing to find 
 optimal low-loss paths in the presence of on-chip temperature variations. 
 With the method of linear function approximation, the proposed approximate
  Q-routing does not require Q-tables which are necessary in traditional ta
 ble-based Q-routing. Simulation results of an 8x8 mesh-based optical NoC u
 nder a set of synthetic traffic patterns and real applications show that t
 he proposed approximate Q-routing can converge faster and its optimization
  effect is very close to the best optimization effect of the traditional t
 able-based Q-routing.\n\nTag: Workshop Reg Pass, Architectures, Datacenter
