The evolution of integrated circuit technology is causing system designs to move towards communication-based architectures. However, metallic interconnect networks (networks-on-chip) can be very costly in terms of power and silicon area and can thus become a bottleneck in system on chip design. Integrated optical networks-on-chip could be good candidates to overcome predicted interconnect limit...

The paper presents a novel Optical Network on Chip (ONoC) relying on the multi-level optical layer design paradigm and called “OMNoC”. The proposed ONoC relies on multi-level microring resonator allowing efficient light coupling between superposed waveguides. Such microring resonator avoids using waveguide crossing, which contribute to reduce propagation losses. Preliminary experimental results...

nowadays network-on-chips is used instead of system-on-chips for better performance. this paper presents a new algorithm to find a shorter path, and shows that genetic algorithm is a potential technique for solving routing problem for mesh topology in on-chip-network.

Optical network on chip (ONoC) architectures are emerging as potential contenders to solve both physical (routing, wire congestion) and performance (bandwidth, latency) issues in future computing architectures. In this work, we present a scalable and fully connected ONoC topology for multiple-core and heterogeneous SoCs. We show that it is possible, through careful design of network interfaces,...

Nanoscale CMOS technologies are posing new network on chip concepts to IC designers. However, the electronic network on chip design faces many problems like energy consumption, long delay and limited bandwidth. Hence, optical network on chip appears as a good candidate to solve these problems. The advances in nanophotonic technology make it more realistic. A new sparse mesh is proposed for opti...

as technology scales deep into the nanometer regime, on-chip communication becomes more susceptible to transient noise sources, such as crosstalk, external radiation, and spurious voltage spikes. the network on chip s modularity and reusability has brought about the use of error control methods to address transient errors in network on chip links.in this work, we design a fault tolerance router...

Photonic interconnect can provide ultra-high bandwidth with low power consumption, which makes Optical Network-on-Chips (ONoCs) a promising alternative for the nextgeneration high performance chip multiprocessors. To make better use of the optical interconnect, Wavelength Division Multiplexing (WDM) is commonly used to provide high bandwidth and decrease the contention possibility. In this pape...
