4.4. Integrate XVDPU and Multiscaler Kernels in the Platform¶

4.4.1. Prerequisites¶

Reference Design source files
Vitis Unified Software Platform 2022.2 (include AIE tool chain)

4.4.2. Build Flow Tutorial¶

Clone the Reference Design Files:

Skip this step if the design has already been cloned and extracted to a working directory

Clone the VCK190 PCIe TRD repository using the following command

git clone --branch 2022.2 --recursive https://github.com/Xilinx/vck190-pcie-trd.git

The directory structure is described in the Introduction Section

Set up the Vitis toolchain:

To set up the Vitis toolchain, run the following commands:

source $XILINX_VITIS/settings.sh
export XILINXD_LICENSE_FILE=<path to where the aiecompiler license file is installed>

Implement platform design with xvdpu and multiscaler accelerators:

To create the platform design with accelerators integrated, run the following Makefile:
```
cd $working_dir
make overlay PFM=vck190_mipiRxSingle_hdmiTx OVERLAY=xvdpu
```
The Makefile implements the following:
- Builds the xvdpu kernel which has a PL and AIE portion. The RTL HDL files are converted to xvdpu.xo kernel format and the file libadf.a is provided as an input describing the AIE elf, cdo, and graph.
- Builds the multiscaler kernel by synthesizing the HLS IP and converting it to .xo kernel format.
- Integrates the above kernels into the vck190_mipiRxSingle_hdmiTx design using the Vitis linker. Generates binary_container_1.xclbin which contains meta data describing the kernels and platform. Generates a new XSA that includes the updated PDI.
Note: If Create the Vitis Platform tutorial is not run before this, then this Makefile also generates the Vitis platform.
The following is a list of important output products:
- Vivado project with integrated kernels: $working_dir/overlays/xvdpu/kernels/_x/link/vivado/vpl/prj/prj.xpr
- XSA required for building the Petalinux BSP: $working_dir/overlays/xvdpu/kernels/binary_container_1.xsa The XSA contains the updated PDI with the accelerators added into the platform design and the merged AIE binary.The XSA is required to build the final boot image BOOT.BIN in PetaLinux.
- The xclbin that contains the platform and kernel meta data needed by XRT: $working_dir/overlays/xvdpu/kernels/binary_container_1.xclbin
