Abstract

3D integrated circuit was presented as a new solution to enhance the efficiency and expand the capabilities of modern integrated circuit as well. Studies have shown that in comparison with 2D NoCs, the proposed 3D NoC offers a lower power consumption, shorter delay and high performance due to the reduction of the connection length in 3D NoCs. In this article, we present a routing algorithm for heterogeneous 3D NoC which distributes the chip traffic in the whole network based on the global congestion information. This is achieved by finding the least congested minimal path between the communicating nodes. For vertical connections, we consider the Through-Silicon-Vias (TSV) and to avoid deadlock, we use two virtual channels. The results show that the proposed mechanism is superior in comparison with the Elevator-First algorithm in the similar working condition.
