However, these algorithms are too computationally intensive to be used routinely, especially for 3D acoustic and elastic modeling cases. In this paper, an inexpensive Field Programmable Gate Array (FPGA) based reconfigurable computing (RC) platform is proposed to accelerate the execution of ordinary secondorder and high‐order FD schemes. Our early experiments demonstrated 4 X ∼ 19 X performance improvements for different FD schemes comparing with their conventional pure software solutions running on a 3.0GHz referential Linux workstation. This RC platform is also consistent with the prevailing PC‐Cluster systems and can achieve much better price‐performance ratio along with much lower power consumption.Permalink: https://doi.org/10.1190/1.2148039FiguresReferencesRelatedDetailsCited ByAn implementation of the acoustic wave equation on FPGAsTamas Nemeth, Joe Stefani, Wei Liu, Rob Dimond, Oliver Pell, and Ray Ergas15 December 2008 SEG Technical Program Expanded Abstracts 2005ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2005 Pages: 2668 publication data© 2005 Copyright © 2005 Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished: 07 Dec 2005 CITATION INFORMATION Chuan He, Guan Qin, and Wei Zhao, (2005), High‐order finite difference modeling on reconfigurable computing platform, SEG Technical Program Expanded Abstracts : 1755-1758. https://doi.org/10.1190/1.2148039 Plain-Language Summary PDF DownloadLoading ..." @default.
