ATS-GPU-OCT

Access to low-level API for customization

For expert-level GPU programmers who want to modify the inner workings of ATS-GPU-OCT 4.1, we offer ATS-CUDA-OCT. Included with ATS-GPU-OCT 4.1, ATS-CUDA-OCT implements OCT signal processing using a lower level API, thus making it possible for each part of the OCT signal processing chain to be modified to suit the application needs. ATS-CUDA-OCT is callable only from C/C++ and requires advanced GPU programming, debugging and benchmarking expertise.

    ATS-GPU Change Log

    This file contains all important changes to ATS-GPU

    [4.1.0] - 2020-3-4

    Added

    • API to query compute capability.
    • API call to return libraries version number.
    • ATS-CUDA-OCT requires an AlazarTech board in order to be used.
