Towards Dilated Placement of Dynamic NoC Cores

Authors: Branislav Hredzak and Oliver Diessel

Abstract

Instead of mapping application task graphs in a compact manner onto reconfigurable devices using a network-on-chip for interconnecting application cores, we propose dilating the mappings as much as the available latencies on critical connections allow. In a dilated mapping, the unused resources between an application's configured components can be used to provide additional flexibility when the configuration needs to change. We motivate the reasons for dilating application task graphs targeted at reconfigurable devices; derive a simulated annealing approach to dilating the placement of such graphs; and present preliminary results of applying the algorithm to synthetic test cases. The method appears to result in successful and meaningful graph dilation and could be further tuned to satisfy desired power constraints.

Enabling RTR for industry

Authors: Oliver Diessel and Shannon Koh

Published in: Dagstuhl Seminar Proceedings, Volume 6141, Dynamically Reconfigurable Architectures (2006)

Abstract

This talk explores the promise of run tme reconfigurable (RTR) technology and makes an attempt to identify critical support elements that need to be put in place in order to overcome barriers to enhanced RTR uptake in industry. We outline a research project underway at the University of New South Wales to develop a positioning satellite receiver that exploits the diversity in satellite signals to mitigate the effects of interference. This project is examined as a case study to motivate the discovery of challenges an industrial organisation faces engineering a dynamically reconfigurable product. Our progress towards the development of a methodology for providing communications infrastructure for module-based applications illustrates one of the efforts necessary to develop useful synthesis tools for RTR applications development. We conclude with suggestions for how the academic community can better assist the commercial development of real applications.
