Abstract
2D-mesh is widely used in Network-on-Chip as its regular topology and simple layout match the two-dimensional VLSI layout well. Further more, the optical circuit switching (OCS) is introduced to provide higher bandwidth and lower power consumption. However, the undesirable property of OCS is the coarse granularity of resource reservation. It leads to a high blocking ratio and degrades the performance. This paper proposes a multi-wavelength communication strategy and an optical router to solve this problem. The simulation results show that the strategy improves the performance in terms of end-to-end delay and throughput.
