Proceedings ArticleDOI
Crosstalk noise and bit error rate analysis for optical network-on-chip
Yiyuan Xie,Mahdi Nikdast,Jiang Xu,Wei Zhang,Qi Li,Xiaowen Wu,Yaoyao Ye,Xuan Wang,Weichen Liu +8 more
TL;DR: It is found that crosstalk noise significantly limits the scalability of ONoCs, and a novel compact high-SNR optical router is proposed to improve the maximum ONoC size to 8×8.
Proceedings ArticleDOI
A NoC Traffic Suite Based on Real Applications
TL;DR: Experimental results show that MCSL benchmark suite can be used to study NoC characteristics more accurately than traditional random traffic patterns.
Journal ArticleDOI
3-D Mesh-Based Optical Network-on-Chip for Multiprocessor System-on-Chip
Yaoyao Ye,Jiang Xu,Baihan Huang,Xiaowen Wu,Wei Zhang,Xuan Wang,Mahdi Nikdast,Zhehui Wang,Weichen Liu,Zhe Wang +9 more
TL;DR: This paper presents a 3-D mesh-based ONoC for MPSoCs, and new low-cost nonblocking 4 × 4, 5 × 5, 6 × 6, and 7 × 7 optical routers for dimension-order routing in the 3- D mesh- based O noC, and proposes an optimized floorplan.
Journal ArticleDOI
Crosstalk Noise in WDM-Based Optical Networks-on-Chip: A Formal Study and Comparison
Mahdi Nikdast,Jiang Xu,Luan H. K. Duong,Xiaowen Wu,Xuan Wang,Zhehui Wang,Zhe Wang,Peng Yang,Yaoyao Ye,Qinfen Hao +9 more
TL;DR: In the worst case, the crosstalk noise power exceeds the signal power in all three WDM-based ONoC architectures, even when the number of processor cores is small, e.g., 64.
Proceedings ArticleDOI
A Hierarchical Hybrid Optical-Electronic Network-on-Chip
TL;DR: This paper proposes a hybrid optical mesh NoC, HOME, which utilizes optical waveguides as well as metallic interconnects in a hierarchical manner and employs a new set of protocols to improve the network throughput and latency.
