ATS-GMA-OCT OCT Signal Processing Library
■ATS-GMA-OCT is an OCT Signal Processing Library developed by AlazarTech that provides very high-speed floating point FFT capability for data acquired by AlazarTech’s PCI Express waveform digitizers or for user-supplied data. ATS-GMA-OCT must be used with ATS-GMA-BASE
■ATS-GMA-BASE allows users to DMA data from AlazarTech PCI Express waveform digitizers to AMD Radeon Pro Graphi- cal Processing Units (GPUs) at rates up to 6.9 GB/s with a latency as low as 100 μs. ATS-GMA-BASE does not use any host memory buffers for temporary storage
■With this very low latency and high speed data transfer, it is now possible to acquire signals at 4 GS/s sample rate and 12 bit resolution and DMA the gapless stream to a GPU for complex signal processing.
■ATS-GMA-OCT provides out-of-the-box OCT imaging. It contains floating point FFT routines that have been optimized to provide the maximum number of FFTs per second. Kernel code running on the GPU can do zero-padding, apply a windowing function, do a floating point FFT, calculate the amplitude and convert the result to a log scale. It is also possible to output phase information.
