This out of tree (OOT) module for GNU Radio contains code to provide an interface to call NVIDIA's TensorRT deep learning binaries from a GNU Radio flowgraph. TensorRT allows for deep learning networks to be optimized for inference operations on an NVIDIA graphics processing units (GPU).

For an example of how to use GR-Wavelearner, see our presentation here

RAPIDS is an NVIDIA open source project to GPU accelearate data science. cuSignal is a GPU accelerated version of scipy.signal.


The RAPIDS cuSignal project leverages CuPy, Numba, and the RAPIDS ecosystem for GPU accelerated signal processing. In some cases, cuSignal is a direct port of Scipy Signal to leverage GPU compute resources via CuPy but also contains Numba CUDA kernels for additional speedups for selected functions. cuSignal achieves its best gains on large signals and compute intensive functions but stresses online processing with zero-copy memory (pinned, mapped) between CPU and GPU.
