This paper presents the architecture of a router designed to efficiently support traffic generated by multimedia applications. The router is targeted for use in clusters and LANs rather than in WANs, the latter being served by communication substrates such as ATM. The distinguishing features of the proposed router architecture are the use of small(More)
–Distributed Video Coding (DVC) is an increasingly popular approach among the researchers in video coding during past few years due to its attractive and promising features. In DVC, the majority of the computational complexity has been shifted from encoder to the decoder in comparison to its conventional counterparts, including MPEG and H.26x enabling a(More)
Designers of large parallel computers and clusters are becoming increasingly concerned with the cost and power consumption of the interconnec-tion network. A simple way to reduce them consists of reducing the number of network components and increasing their utilization. However, doing so without a suitable congestion management mechanism may lead to(More)
—Virtual channels (VCs) are a popular solution for the provision of quality of service (QoS). Current interconnect standards propose 16 or even more VCs for this purpose. However, most implementations do not offer so many VCs because it is too expensive in terms of silicon area. Therefore, a reduction of the number of VCs necessary to support QoS can be(More)
