Abstract :
3D IC technology drives Network-On-Chip (NoC) design on towards 3D trend and relevant multi-core system further development. However, most recent researches still focus on the fundamental 3D Mesh structure and have no convincible traffic pattern models in realistic applications. In this paper, we p resent a complete design framework of a Distributed Shared Memory homogenous multi-core system based on 3D Torus interconnects. A Gray code routing mechanism is also proposed to solve deadlock. In addition, we evaluate the 3D Torus system with both Synthetic traffic (uniform and transpose pattern) and real parallel multi-thread benchmark. Comparing with 3D Mesh, our experimental results demonstrate a significant reduction in the average packet latency and higher throughout put as well as a major improvement of execution cycles in typical thermal-aware IP mapping methods in 3D Torus multi-core system.
