Abstract
The thermal issue is important for 3D Network-on-Chip systems. To ensure the thermal safety, the near-overheat routers are throttled and the 3D topology becomes Non-Stationary Irregular Mesh (NSI-Mesh). To ensure the successful packet delivery in the NSI-Mesh, Transport Layer Assisted Routing (TLAR) scheme was proposed. It has better performance than the conventional routing approaches for NSI-Mesh. However, it still suffers significant traffic congestion in the bottom chip layer due to the insufficient lateral path diversities. To achieve more balanced traffic, we propose a Traffic-balanced Topology-aware Multiple Routing Adjustment (TTMRA). The experimental results show that the proposed TTMRA can improve 81.8% ∼ 102.3% network throughput than TLAR scheme. © 2012 IEEE.
