vector addition using Xilinx Run-time (XRT)

Vector Addition Example

This repository shows an example of the vector addition accelerator on PYNQ. This is based on 2019.1 or later tools on ZCU104 board.

Compiling hardware project

The hardware project has to be compiled on an X86 host. You probably want to source SDx and XRT settings before you build the hardware project.

make xclbin

The make process is going to pick up the scout platform you specified in the Makefile, or you can provide that platform as an additional argument to the make process.

After some time, you should be able to see the *.xclbin file generated. You need to copy *.xclbin and the bitstream onto the board.

To rebuild the hardware project, you can run make cleanall first to remove the Vivado project completely.

Compiling software executable

The software executable needs to be compiled on the board (or in a QEMU environment).

make elf

The executable can then be run on the board. Make sure you at least load the bitstream once on the board before you run the program.

./vadd.elf

You should be able to see some messages like TEST PASSED in your terminal. To rebuild the software executable, you can run make clean first to just remove the target binaries.
