Kria™ KV260 Vision AI Starter Kit Tutorial

Integrating the overlay into the Platform

Integrating the overlay into the Platform

Introduction:

This document provides the steps to integrate the overlay consisting of accelerated functions into the platform.

Prerequisites:

  • Vitis Unified Software Platform 2021.1

Accessing the Tutorial Reference Files

Note: Skip the following steps if the design files have already been cloned and extracted to a working repository

  1. To access the reference files, type the following into a terminal:

    git clone --branch release-2021.1 --recursive https://github.com/Xilinx/kria-vitis-platforms.git
    
  2. Navigate to the kv260-vitis which is the working directory.

Integrating an overlay (accelerator functions) into a Vitis Extensible platform

  1. Go to the working directory

    cd $working_dir/
    
  2. To compile and integrate the overlay into the platform, run the following command. The Makefile calls a lower level Makefile to run Vitis. If a platform is not already available it builds that as well.

    make overlay OVERLAY=<application_name>
    

    Applications currently supported are listed below

Application name Platform used
smartcam kv260_ispMipiRx_vcu_DP
aibox-reid kv260_vcuDecode_vmixDP
defect-detect kv260_ispMipiRx_vmixDP
nlp-smartvision kv260_ispMipiRx_DP
  1. The generated bitfile and xclbin will be located at

    $working_dir/overlays/examples/<application_name>/binary_container_1/link/int/system.bit   
    $working_dir/overlays/examples/<application_name>/binary_container_1/*.xclbin
    

    The xclbin and bitfile generation may take couple of hours depending on the system specification. They will be used to build the Petaliunx image
