Digital Signal Processing using Stream High Performance Computing: A 512-input Broadband Correlator for Radio Astronomy
J. Kocz, L. J Greenhill, B. R. Barsdell +16
A "large-N" correlator that makes use of Field Programmable Gate Arrays and Graphics Processing Units has been deployed as the digital signal processing system for the Long Wavelen…
Pulsar Observations Using the First Station of the Long Wavelength Array and the LWA Pulsar Data Archive
K. Stovall, P. S. Ray, J. Blythe +7
We present initial pulsar results from the first station of the Long Wavelength Array (LWA1) obtained during the commissioning period of LWA1 and early science results. We present…
A Scalable Hybrid FPGA/GPU FX Correlator
J. Kocz, L. J. Greenhill, B. R. Barsdell +8
Radio astronomical imaging arrays comprising large numbers of antennas, O(10^2-10^3) have posed a signal processing challenge because of the required O(N^2) cross correlation of si…
Imaging at Both Ends of the Spectrum: the Long Wavelength Array and Fermi
G. B. Taylor, The LWA Collaboration
The Long Wavelength Array (LWA) will be a new multi-purpose radio telescope operating in the frequency range 10-88 MHz. Scientific programs include pulsars, supernova remnants, gen…
