For many years, computer designers benefitted from Moore's law and Dennard scaling to significantly improve the speed of single-core processors. The failure of Dennard scaling pushed the computer industry toward homogenous multicore processors for the performance improvement to continue without significant increase in power consumption. Unfortunately, even homogeneous multicore processors cannot offer the level of energy efficiency required to operate all the cores at the same time in today's and especially tomorrow's technologies. As a result of lack of energy efficiency, not all the cores in a multicore processor can be functional at the same time. This phenomenon is referred to as dark... 

Nowadays networks-on-chip are emerging as a hot topic in IC designs with high integration. Much research has been done in this field of study recently, e.g. in routing algorithms, switching methods, VLSI Layout, and effects of resource allocation on system performance. On the other hand, three-dimensional integrated circuits allow a time-warp for Moore's Law. By vertically stacking two or more silicon wafers, connected with a high-density, high-speed interconnect, it is now possible to combine multiple active device layers within a single IC. In this paper, we examine performance and power consumption in a three dimensional network-on-chip structure under different types of traffic loads,...
