ATS-GPU - Real
Time DSP Software
ATS-GPU is a software framework
developed by AlazarTech to allow
users to do real-time signal
processing using an Open CL
compatible Graphical Processing
Unit (GPU). Input to the GPU can
either come from an AlazarTech
PCI Express waveform digitizer
or from user-supplied data.
Fundamentally, ATS-GPU solves
the problem of transferring data
from a waveform digitizer to a
GPU at very high speeds.
A floating point FFT routine built
into ATS-GPU has been
benchmarked at 235,000 FFTs per
second for 2048 points on one
input. Ideal for Optical Coherence Tomography
(SS-OCT).
Benchmarks also showed that
users can keep up with 500 MS/s
sampling on one channel for 2048
point streaming FFTs.
