CUDA Plugins

This folder contains CUDA-accelerated OpenBR plugins. They are structured in the following format.

File Structure

We will use a plugin called CUDAPlugin as an example.

Each plugin has 3 files associated with it: a CUDA file, CPP file, and HPP header file.

cudaplugin.cu
cudaplugin.cpp
cudaplugin.hpp

The .cu file contains CUDA kernel functions and the corresponding wrapper functions that directly call the kernel functions. The .cpp files contain the OpenBR standard plugin declaration. Functions in this file call the wrappers. The .hpp contains header declarations for the CUDA wrapper functions so the .cpp file knows how to call them.

CUDA Files

All functions for a particular CUDA plugin are defined in a namespace of that plugin's name which is defined within br::cuda namespace. For example, if we have a plugin called CUDAPlugin, both wrapper and kernel functions should be globally defined within br::cuda::cudaplugin.
