SCF: A Framework for Task-Level Coordination in Reconfigurable, Heterogeneous Systems
Vikas Aggarwal, Greg Stitt, Alan George, Changil Yoon
Article No.: 7
DOI: 10.1145/2209285.2209286

Heterogeneous computing systems comprised of accelerators such as FPGAs, GPUs, and manycore processors coupled with standard microprocessors are becoming an increasingly popular solution for future computing systems due to their higher performance...

Dynamic Defragmentation of Reconfigurable Devices
Sándor P. Fekete, Tom Kamphans, Nils Schweer, Christopher Tessars, Jan C. van der Veen, Josef Angermeier, Dirk Koch, Jürgen Teich
Article No.: 8
DOI: 10.1145/2209285.2209287

We propose a new method for defragmenting the module layout of a reconfigurable device, enabled by a novel approach for dealing with communication needs between relocated modules and with inhomogeneities found in commonly used FPGAs. Our method is...

Statistical Timing and Power Optimization of Architecture and Device for FPGAs
Lerong Cheng, Wenyao Xu, Fang Gong, Yan Lin, Ho-Yan Wong, Lei He
Article No.: 9
DOI: 10.1145/2209285.2209288

Process variation in nanometer technology is becoming an important issue for cutting-edge FPGAs with a multimillion gate capacity. Considering both die-to-die and within-die variations in effective channel length, threshold voltage, and gate oxide...

Constraint Programming Approach to Reconfigurable Processor Extension Generation and Application Compilation
Kevin Martin, Christophe Wolinski, Krzysztof Kuchcinski, Antoine Floch, François Charot
Article No.: 10
DOI: 10.1145/2209285.2209289

In this article, we present a constraint programming approach for solving hard design problems present when automatically designing specialized processor extensions. Specifically, we discuss our approach for automatic selection and synthesis of...
