Round robin arbiter (RRA) is a critical block in nowadays designs. It is widely found in System-on-chips and Network-on-chips. The need of an efficient RRA has increased extensively as it is a limiting performance block. In this paper, we deliver a comparative review between different RRA architectures found in literature. We also propose a novel efficient(More)

All-optical packet switching (OPS) is one of the promising technologies for the next generation of optical networks. It realizes the packet switching in optical domain that eliminates optical-electrical and electrical- optical conversions. One of the main components in an OPS network is the optical interconnect that provides the basic functionality of(More)
Simultaneous power exchange between two input signals, has been theoretically and experimentally demonstrated based on two phenomena: Four Wave Mixing (FWM) in High-Linear Dispersion Shifted Fiber (HNL-DSF) and Three Wave Mixing (TWM) in NonLinear Photonic Crystals (NL-PC). These phenomena have been used in many applications in WDM optical networks such as,(More)
Optical Packet Switching (OPS) is a promising technology to enable next-generation high-speed IP networks. One of the main components in an OPS network is the optical switch architecture that provides the basic functionality of switching packets from input ports to the desired output ports while maintaining data in the optical domain. In asynchronous OPS(More)
SUMMARY Increasing demand in data-traffic has been addressed over the last few years. It is expected that the data-traffic will present the significant part of the total backbone traffic. Accordingly, much more transmission systems will be required to support this growth. A free space optic (FSO) communication is the greatest promising technology supporting(More)
In this paper, a high-performance priority encoder is presented by using full custom approach. The proposed encoder provides both high- and low-priority functional with scalable design structure through a parallel look-ahead structure. A prefixing architecture is applied to minimize the critical path propagation delay and maximize the operating frequency.(More)
In this paper, the influence of LED video walls on wireless microphones is discussed. First the standard-compliant EMC measurement procedures are presented, which are needed to measure interference of such equipment. Afterwards measurements of the UHF spectrum at events and at a LED wall manufacturer were made to explore the actual failures caused by video(More)
