Many complex systems require the use of floating point arithmetic that is exceedingly time consuming to perform on personal computers. However, floating point operators are also hardware resource intensive and require longer latencies than fixed point operators to complete. Due to the reduced logic density of FPGAs relative to ASICs, it is often only possible to accelerate a portion of a floating point application in hardware.
This talk presents an application-specific architecture for the hardware acceleration of a complete Fourier Integral Operator (FIO) kernel used in seismic imaging on a multi-FPGA platform. The design utilizes several floating point computing elements (CEs) to calculate the FIO kernel in parallel stages on multiple FPGAs. A detailed study of floating point CEs, including a Fast Fourier Transform (FFT) CE, and a complete FIO prototype implementation, including design decisions and implementation results on the BEE2 platform, is described.
BIOGRAPHY:
Dr. Lesley Shannon received a B.Sc. in Electrical Engineering from the University of New Brunswick in 1999. She then attended the University of Toronto (U. of T.) for both her Masters and Doctoral studies in Computer Engineering, obtaining her M.A.Sc. in 2001 and her Ph.D. in 2006.
Dr. Shannon joined Simon Fraser University's School of Engineering Science in the fall of 2006 as an Assistant Professor. Her research interests include alternative computing architectures such as reconfigurable computing, SoCs, NoCs, embedded computing, and application-specific architectures; programming models and environments; on-chip Computer Aided Design (CAD) tools; and system design methodologies.
