Abstract

Clos network, a family of multistage networks, is applied to build scalable commercial multiprocessors with thousands of nodes in macro systems. An MPSoC is a system on- chip a VLSI system that incorporates most or all the components necessary for an application that uses multiple programmable processors as system components. This paper presents the design and simulation of clos network that provides the contention free permutation in multiprocessor system on chip (MPSoC).The proposed clos network employs an ID matching scheme with pipelined circuit switching and dynamic path setup scheme based on Exhausted Profitable backtracking (EPB) under a multistage network topology. Due to the pre-configured circuit-switched data paths, applying a source-synchronous data transfer scheme is feasible. The ID matching scheme offers a contention free routing from unauthorized users. The pipelined circuit switching approach offers a guarantee of permutated data. The circuit-switching approach offers a guarantee of permuted data and its compact overhead enables the benefit of stacking multiple networks. The dynamic path setup scheme enables run time path arrangement for arbitrary traffic permutation.

Abstract

Transportation is regarded as an index of economic, social and commercial progress of a country. An adequate and safe transportation is indispensible for economic and social progress of a nation and the world as a whole. Bridges are key components of a transportation infrastructure and restoring their health is an important criteria. This paper deals with a proposal for rehabilitation measures for an existing railway bridge in a southern city in India. The existing bridge faces many problems like smaller headroom, corroded steel plates and needs immediate rehabilitation. Hence an attempt has been made in this work to redesign the existing riveted type plate girder as a welded type plate girder with increased headroom by providing gradients at both the sides of the bridge. A Subway bridge for carriage way under the railway bridge has been introduced to provide a gradual gradient for the carriageway and the drainage system has been designed accordingly.
