Traffic-Aware Selection Strategy for Application- Specific 3D NoC

Three-dimensional stacking of silicon layers is emerging as a promising solution to handle the design complexity and heterogeneity of Systems on Chips (SoCs). The use ofNetworks on Chips (NoCs) to connect components in a 3D chip is a necessity. NoC performance largely depends on theunderlying deadlock-free and efficient routing algorithm. In this paper a novel selection strategy LATEX1, is proposed that can be used with any adaptive routing algorithm forspecified applications on 2D or 3D topologies. The selection function, which decides the final output channel when a setof admissible output channels exist, is essential for an adaptive routing algorithm. The objective of the proposed selection strategy is to efficiently balance traffic load andreach better performance. Experimental results show that the proposed selection strategy applied to routing algorithm improves average delay and throughput
