Traffic- and Thermal- Balanced Adaptive Beltway Routing in Thermal Aware 3d Noc Systems
نویسندگان
چکیده
The traffic and thermal problems of high performance three-dimensional Network-on-Chip (3D NoC) system become more unbalanced because of chip stacking and applied minimal routing algorithm. To make the temperature under a certain thermal limit, the overheat nodes are throttled by run-time thermal management (RTM). Therefore, the network topology becomes a Non-Stationary Irregular Mesh (NSI-Mesh) and leads to heavy traffic congestion around the throttled nodes. Because of the traffic imbalance in the network, the system performance degrades sharply as temperature rises. In this paper, a Trafficand Thermal-balanced Adaptive Beltway Routing (TTABR) is proposed to balance both the traffic and temperature distribution in the network. The proposed TTABR can be applied to both NSI-Mesh and regular mesh. The experimental results show that the proposed TTABR can achieve more balanced traffic and thermal distribution. Besides, the network throughput is improved by around 3.4~126.7%.
