Abstract:Reconfigurable computing based on FPGAs provides an alternative
route to parallel computing where fine grained synchronization and
parallelism can be achieved with lower resources and higher
performance than just microprocessor clusters or GPUs. In this
presentation we will describe how a simulation of the propagation of
IR radiation through the atmosphere has been accelerated using
FPGAs. The major contributions described are fast medium precision
random number generation, image convolution with kernels that change
with each pixel and the application of the properties of linear
operators to reduce computational complexity of algorithms to
compute phase distortion attributable to atmospheric turbulence to
make them suitable for FPGA acceleration.
Biography:David Kearney is an academic staff member in School of Computer and
Information Science at University of South Australia. He is the
program director for research degrees. He leads the Systems
Architecture and Security Group and is director of the
Reconfigurable Computing Laboratory . His research is focused at
present on reconfigurable computing. He is particularly interested
in operating systems for reconfigurable computing, languages for
expressing reconfigurable applications, clusters of reconfigurable
computers and applications of reconfurable computing. His research
thus includes the operating system ReconfigME, the language Hardware
Join Java , the Insilice reconfigurable cluster and applications of
reconfigurable computing relating to Unihabited Airbourne Vehicles
(UAVs), infrared image processing and tracking and the seaching of
bioinoformatic databases. His qualifications include Bachelor of
Engineering (with first class honours) from University of New South
Wales; Master of Engineering (by research) from University of South
Australia; and PhD from Queensland University of Technology.
Vinay Sriram is a PhD student under A/Prof Keraney's supervision
within the Reconfigurable Computing Laboratory.
