The Adaptive Thermal and Traffic-Balanced Routing algorithm based on temperature analysis and traffic statistics

Abstract

Recently, 3D NOC is proposed as an efficient architecture to optimize system performance. However, its die-stacking architecture further results in severe heat and traffic congestion problem. In the view of that, a new Adaptive Thermal and Traffic Balanced ZXY Routing algorithm (ATTBR) is proposed to solve the problems. Experiments has shown that, in the 4 × 4 × 4 3D Mesh, ATTBR has a better throughput and average delay performance achieves 34.67% and 14.85% increment in Temperature-Traffic Balance Product which indicates thermal and traffic balance performance, compared to Regional avoidance routing algorithm and Vertically Downward Routing algorithm.

Collaborative thermal- and traffic-aware adaptive routing scheme for 3D network-on-chip systems

“…The thermal issues may degrade the system performance and cause lower reliability of the system. In order to tackle the thermal issues in 3D NoC-based systems, dynamic thermal management [8,9,10,11,12,13] and adaptive routing strategy [14,15,16,17,18,19] have been proposed.…”

ArR-DTM: A routing-based DTM for 3D NoCs by adaptive degree regulation

“…By contrast, routing based DTMs [8,9] alleviate the thermal issues by balancing the thermal distribution. Rahmani et al [8] proposed a thermal-aware routing strategy for bus-mesh hybrid 3D NoC.…”

“…The adaptiveness provided is seemingly limited and only two routing states are available. Our previous work [9] has proposed a thermal and traffic balanced algorithm based on the global sharing information, but introduces additional bandwidth consumption, and thus additional power consumption.…”
