Firefly: illuminating future network-on-chip with nanophotonics
Yan Pan,Prabhat Kumar,John Kim,Gokhan Memik,Yu Zhang,Alok Choudhary +5 more
- 20 Jun 2009
TL;DR: Firefly is a hybrid, hierarchical network architecture that consists of clusters of nodes that are connected using conventional, electrical signaling while the inter-cluster communication is done using nanophotonics - exploiting the benefits of electrical signaling for short, local communication while nanophotinics is used only for global communication to realize an efficient on-chip network.

- 10 May 2009
TL;DR: Cost-efficient implementations of concentration are described and it is shown how external concentration provides a significant reduction in complexity compared to previous assumed integrated (high-radix) concentration while degrading overall performance by only 10%.

TL;DR: This work studies the power impact of scan chain testing for the ISCAS89 benchmarks and presents an optimal formulation for minimal-duration temperature-constrained test scheduling, which improves on the test schedule time of the best existing algorithm by 10.8% on average.
Accelerating data mining workloads: current approaches and future challenges in system architecture design
TL;DR: Experiments have shown that heterogeneous architectures employing GPUs or FPGAs can result in significant application speedups over homogenous CPU‐based systems, while increasing performance per watt.
A status-quo review on management of root knot nematode in tomato
TL;DR: The root-knot nematodes (RKN) are a significant threat to agricultural productivity among many biotic challenges as discussed by the authors and contribute as an exacerbating agent for the introduction of bacterial and fungal pathogens.
