Prestack Kirchhoff Time Migration On High Performance Reconfigurable Computing Platform

A reconfigurable computing (RC) platform called SPACE (Seismic data Processing Accelerator with reConfigurable Engine) is proposed to accelerate the execution of 3D prestack Kirchhoff time migration (PSTM) based on the optimized 6 order NMO Correction technology (Sun et. al. 2002). Our simulations demonstrated up to 22 X performance improvement on the proposed RC platform comparing with the pure software solution running on a P4 2.4 GHz referential Linux workstation. This RC platform is also consistent with prevailing PC-Cluster systems and can achieve much better price-performance ratio along with much lower power consumption.
