Abstract: AMBAR is a message passing multiprocessor system based on a multistage crossbar network. In this paper, the design of a crossbar controller for AMBAR system is presented. The responsibility of the crossbar controller is to program the crossbar switches creating a path between the source and the destination node. The design is modular, fast, and feasible using current off the shelf com...

We demonstrate an optically controlled 2x2 Crossbar switch suitable for all-optical switching architectures. The switch is based on an Ultrafast Nonlinear Interferometer (UNI) configuration and uses 80 centimeters of highly nonlinear Bismuth Oxide fiber. Error-free operation is demonstrated with 10 and 40 Gb/s input signals, with power penalties in its BAR and CROSS states of less than 0.3 dB a...

In this work, the performance and reliability analysis of a crossbar molecular switch nanomemory demultiplexer is studied and results presented. In particular, we investigate the impact on the performance of a crossbar nanomemory demultiplexer of implementing a combination of error correction coding and multi-switch junction fault tolerance schemes. Results indicate that delay and power scale l...

An optoelectronic router with a shuffle exchange network is presented and enhanced by adding micro-optical-electrical mechanical systems (MOEMS) in the network to add the ability to reconfigure the shuffle network. The MOEMS described here are fully connected any-to-any crossbar switches. The added reconfigurability gives the opportunity to adapt for different common application characteristics...

Heat switches are key elements in the cyclic operation of Adiabatic Demagnetization Refrigerators (ADRs). Several of the types of heat switches that have been used for ADRs are described in this paper. Key elements in selection and design of these switches include not only ON/OFF switching ratio, but also method of actuation, size, weight, and structural soundness. Some of the trade-off are det...

New single-receiver/singletransmitter/singlebuffer node structures for two-connected multihop transparent optical packet-switching network8 with deflection routing are introduced. A ShuBeNet topology an uniform trafic is adopted to compare various shared optical memory schemes and their control algorithms. These simple structures minimize the number of crossbar switches needed at the node and h...

Optoelectronic integrated circuits can support thousands of integrated optical laser diodes and photodetectors bonded to a high-performance CMOS substrate, and can be used in the design of Multi-Terabit optical Local Area Networks. This paper describes the design of an integrated optoelectronic CMOS crossbar switch to interconnect approx. 128 parallel fiber ribbon optical links, each with 12 ch...

This paper presents a modified architecture for a buffered crossbar switch that overcomes the memory bottleneck with only a minor impact on performance. The proposed architecture uses two levels of backpressure with different constraints on round trip time. Buffered crossbars are considered an alternative to bufferless crossbars mainly because the latter requires a complex scheduling algorithm ...

Buffered crossbar switches are special crossbar switches with each crosspoint equipped with a small exclusive buffer. The crosspoint buffers decouple input ports and output ports, and simplify switch scheduling. In this paper, we propose a scheduling algorithm called Fair and Localized Asynchronous Packet Scheduling (FLAPS) for buffered crossbar switches, to provide tight performance guarantees...
