Eecient Multichip Partial Concentrator Switches
نویسنده
چکیده
Due to chip area and pin count constraints, large con-centrator switches sometimes must be partitioned among several chips. This paper presents designs for two mul-tichip partial concentrator switches, both of which follow from a lemma showing that an "-nearsorter is also an (n; m; 1 ? "=m) partial concentrator.

Design of An All-Optical WDM Lightpath Concentrator
A design of a nonblocking, all-optical lightpath concentrator using WOC and WDM crossbar switches is presented. The proposed concentrator is highly scalable, cost-efficient, and can switch signals in both space and wavelength domains without requiring a separate wavelength conversion stage.
متن کاملDesign and Analysis of a Packet Concentrator
Packet concentrators are used in many highspeed computer communication systems such as fast packet switches. In these systems, the time available for concentration is very short. It is therefore desirable to realize the packet concentrators as hardware chips for fast concentration. The knockout concentrator was proposed for hardware realization. In this paper, we improve this concentrator to re...
متن کاملEnergy Considerations in Multichip-Module Based Multiprocessors
Multichip modules permit highly eecient implementation of \tiled" architectures. If the tiles are implemented in submicron CMOS, extremely high computation rates can be achieved, but power dissipation becomes the principal factor limiting achievable levels of integration and performance. This paper describes some examples of tiled architectures, and discusses the feasibility and advantages of r...
متن کاملPerformance of Input-Queued Sparse-Crossbar Packet Concentrators
Packet concentrators are used in shared-memory and knockout switches to select and route packets into individual outputs. Recently, a switch model was introduced to investigate the intrinsic relationship between the switching complexity and traffic characteristics of packet concentrators. Using this model, it was shown that any bipartite packet concentrator with n inputs, m outputs and peak per...
متن کاملFault-Tolerant Arbitration in Multichip Crossbar Switches
A major problem in the design of large multichip crossbar networks is the latency associated with the centralized controller used to arbitrate requests. We present a solution to reduce this latency and also provide fault-tolerance by the use of multiple controllers that can operate concurrently. This paper concentrates on crossbars that are constructed using one-sided crosspoint switches, as su...
