Copy Buffer XRT (XRT native API’s)

This Copy Buffer example demonstrate how one buffer can be copied from another buffer.

KEY CONCEPTS: Copy Buffer

KEYWORDS: copy

This example illustrates the use of Copyr API for deep copy between the two buffer objects if the platform supports a deep-copy. If deep copy is not supported by the platform the data transfer happens by shallow copy.

Contents of bo_a are copied into bo_b.

dst_buffer.copy(src_buffer, copy_size_in_bytes);

The API xrt::bo::copy also has overloaded version to provide a different offset than 0 for both the source and the destination buffer.

EXCLUDED PLATFORMS:

• All NoDMA Platforms, i.e u50 nodma etc

DESIGN FILES

Application code is located in the src directory. Accelerator binary files will be compiled to the xclbin directory. The xclbin directory is required by the Makefile and its contents will be filled during compilation. A listing of all the files in this example is shown below

src/host.cpp
src/vector_addition.cpp

Access these files in the github repo by clicking here.

COMMAND LINE ARGUMENTS

Once the environment has been configured, the application can be executed by

./copy_buffer_xrt -x <vector_addition XCLBIN>
