TURO: A lightweight turn-guided routing scheme for 3D NoCs
Jun Zhou, Huawei Li, Tiancheng Wang, Ying Wang, Xiaowei Li · 2015
Deadlock is a common problem in 3D networks-on-chip. In this paper, we propose a lightweight and deadlock-free turn-guided routing scheme named TURO without requiring any virtual channels, which is a minimal routing guided by a new 3D turn model NeoOE. The theoretical analysis and experimental results show that TURO possesses improved adaptivity, higher performance and lower overhead compared with the state-of-the-art routing schemes using other 3D turn models.
