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…
Limits on GRB Prompt Radio Emission Using the LWA1
K. S. Obenberger, J. M. Hartman, G. B. Taylor +6
As a backend to the first station of the Long Wavelength Array (LWA1) the Prototype All Sky Imager (PASI) has been imaging the sky -26 declination during 34 Gamma Ray…
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…
