3.0 Decimation FIR Filter DSP Design
Developing a DSP algorithm with the AI Engine technology is only one part of the design flow and not necessarily the most complicated one. At the end of the day, the DSP kernels implemented into the AI Engine array have to be connected with the Programmable Logic (PL) datamover kernels and with the ARM A72 CPU host Programmable Subsystem (PS): the PL kernels require AMD Vitis™ HLS as design flow, the PS application requires C/C++ programming with either XRT or OpenCL APIs to manage the kernels at runtime execution on the target board within the PetaLinux OS.
Building a system from scratch like this is not trivial and it is better to have a good starting point that could be adapted with few changes, a sort of "system design template" or "toolbox" to use some improper terminology.
This tutorial explains how to design a DSP algorithm and implement it into the AI Engine domain of the AMD Versal™ device, using the production VCK190 target board and the AMD Vitis 2024.1 Unified software platform design tools.
The DSP algorithm is a decimation FIR filter taken from the Vitis 2024.1 DSP Libraries (for AI Engine).
You will build a system running on the VCK190 board having:
- A DSP kernel implemented on AI Engine domain (the decimation FIR filter)
- Two PL datamover kernels, designed with HLS
- Software application for the ARM host processor using the XRT APIs
- An SD card with PetaLinux OS for booting
As you use this document, it is assumed that you have named this tutorial repository 02-AIE_DSP_with_Makefile_and_GUI and placed it in a certain working directory ${WRK_DIR}. For example, in this case:
export WRK_DIR=/media/danieleb/DATA/2024.1/Vitis-Tutorials/Developer_Contributed.
The organization of the folders tree of this tutorial is illustrated here (with emphasis on the folder related to AI Engine; otherwise, the tree would explode):

-
Everything shown in this project used an Ubuntu 22.04 Desktop with related Vitis 2024.1 release.
-
It is recommended to write the SD card that boots the VCK190 board with the Windows OS utility called Win32 Disk Imager 1.0.
-
Some figures are screenshots related to the earlier release of Vitis and there might be a few differences, although minimal, with the current one.
-
It is recommended that you set correctly the environment before running any script, as described in details in the next subsection 2.3.6. The
*_sample_env_setup.shscripts contain a template to be customized for your needs. -
The run_all.sh must always be launched only after all the variables of previous script have been set at least once, and only from the files folder, which has to be your current directory.
-
Read the entire README.md document carefully before launching any script or Makefile.
In case you get some unexpected errors during the execution of the scripts, once pre-process all the*.sh, *.cpp, *.h files with the dos2unix utility.
In that case, run the following commands from your Ubuntu host PC:
#sudo apt-get install dos2unix
cd <WRK_DIR> #your working directory
cd 02-AIE_DSP_with_Makefile_and_GUI/files
source scripts/dos2unix_all.shYou need the following archives from either AMD/Xilinx Download or GitHub websites, in particular:
-
From Vitis (SW Developer) Downloads area, take the 2024.1 Vitis Installer (it makes the Vitis install process easy) and the 2024.1 Vitis Update (if any).
-
From Vitis Embedded Platforms area, take the Common Images for Embedded Vitis Platforms 2024.1.
-
From PetaLinux area, take the 2024.1 PetaLinux Tools Installer.
-
Go to the bottom of PetaLinux 2024.1 - Product Update Release Notes and Known Issues and take 2024.1_PetaLinux_Package_List.xlsx file, which contains all the packages needed by PetaLinux into your Ubuntu OS computer (install all of them before installing PetaLinux).
-
Go to the Xilinx GitHub page and zip both the Vitis Libraries and Vitis Tutorials with branch related to this 2024.1 release.
-
Go to the AMD Alveo™ Packages area, select release 2024.1 and Ubuntu 22.04 OS, and then take the Xilinx Runtime (XRT) archive.
At the end, you should have the following files:
Xilinx_Unified_2024.1_*_Lin64.bin
Xilinx_Vivado_Vitis_Update_2024.1_*.tar.gz
xilinx-versal-common-v2024.1_*.tar.gz
Vitis_Libraries-main.zip
Vitis-Tutorials-2024.1.zip
xrt_202410.*-amd64-xrt.deb
First, install the basic version of Vitis 2024.1 via the installer Xilinx_Unified_2024.1_*_Lin64.bin. Then add the update Xilinx_Vivado_Vitis_Update_2024.1*.tar.gz. Everything is placed in the folder /tools/Xilinx/.
You might need sudo privilege to install tools on these folders, primarily /tools and /opt, unless you change the ownership and group of folders accordingly.
If you created the /tools directory as a super-user (or root, or with sudo), whatever you want to write or install there can only be done by the root super-user.
This is a basic Linux OS behavior. However, you can change the group and owner so that you can do what you like as a normal user, the way you do it in your $HOME directory.
So, if you run the following commands (and you need sudo):
sudo su
mkdir /tools
mkdir /opt
# -R stays for recursively on each subfolder
chown -R you_user_name /tools
chgrp -R you_user_name /tools
chown -R you_user_name /opt
chgrp -R you_user_name /opt
exitThen you can install the above tools and archives without sudo privilege, just as a normal user.
As a last cross-check, if you installed the tools as a normal user, you should see the hidden folder .Xilinx inside your $HOME directory. If you installed them as a super-user, you should see
the hidden folder .Xilinx inside your /root directory.
In case of installation done with the sudo privilege, there seems to be only a small issue with one line in the script installLibs.sh:
su - $user -c "touch $logFile; chmod 777 $logFile"The touch and chmod commands can not be executed because the logfile is located below the /root directory and the shell was switched to a normal user without root privileges.
This means that the script assumes that the installation was done without root privileges. That line in the script could be replaced by the following commands:
sudo touch $logFile
sudo chmod 777 $logFileIn conclusion, either the installation had root privileges (sudo) and the installLibs.sh needs to be changed, or the installation was done as a normal user.
You have to install this archive xilinx-versal-common-v2024.1_*.tar.gz in the folder /opt/xilinx/common/ folder (which has to be into an ext4 file system, not on an NTFS one).
Then, you have to execute the following commands as a normal user, according to what is discussed in the previous subsection:
cd /opt/xilinx/common/xilinx-versal-common-v2024.1/
chmod 777 ./sdk.sh # if needed
./sdk.sh -p -y -d .Check if you need to decompress the file rootfs.ext4.gz directly.
You can then remove the sdk.sh file to save storage space.
The easiest way to download XRT was from the ALVEO site. Select the ALVEO U200 card and then the Ubuntu 22.04 OS to arrive at this link.
Then install the archive via the following command:
sudo apt install --reinstall ./xrt_<version>.debTo set xrt into your terminal, you need the following command:
source /opt/xilinx/xrt/settings.shwhich is also in the *_sample_env_setup.sh scripts.
WARNING: You cannot install PetaLinux into an NFS driver; otherwise, the install process ends with a non-predictable error message.
Before installing petalinux, check in the Excel foil 2024.1_PetaLinux_Package_List.xlsx what all packages petalinux requires. Once done, install the missing ones.
#create the destination folder
sudo mkdir /petalinux_2024.1
#change permissions
$ chmod 777 ~/Downloads/petalinux-v2024.1-*-installer.run
$ ~/Downloads/petalinux-v2024.1-*-installer.run -d /petalinux_2024.1

To set petalinux into your terminal, you need the following command:
source /petalinux_2024.1/settings.shwhich was also placed in the script *_sample_env_setup.sh.
The *_sample_env_setup.sh scripts contain a template to be adapted by the user to set the tools environment for designing an embedded system on the VCK190 target board.
Once done, call the script with the following command:
cd <WRK_DIR> #your working directory
cd 02-AIE_DSP_with_Makefile_and_GUI/files
# set your environment
source files/scripts/<YOUR_OWN>_sample_env_setup.shIn this section, you will build the decimation FIR filter DSP system using the Vitis GUI. The PS application will apply XRT APIs. The OS is PetaLinux.
Note that the classic Vitis IDE (Eclipse-based) has been deprecated and will be removed in a future release, being it replaced by the new Vitis Unified IDE. If you want to use the classic IDE you have to call it with vitis --classic command as in the following:
cd <WRK_DIR> #your working directory
cd 02-AIE_DSP_with_Makefile_and_GUI/files
# set your environment
#source files/scripts/<YOUR_OWN>_sample_env_setup.sh
# call the Vitis GUI

The Versal Custom Thin Platform Extensible System tutorial has the following aspects to be considered:
- It is always well-maintained and promptly updated along the various Vitis releases.
- By default, it generates a
sd_card.imgfile withpetalinuxfile system on it and the SD card has only one partition (FAT32). - It applies a hierarchy of
Makefilesthat should enable an "easier" customization of the system to be designed, without touching or modifying the directories structure and the Makefile themselves too.
Few notes to be mentioned besides what is already reported in its related README.md file:
-
Do not use the
sd_card.imgfile generated in thepackage_output_hw. On the contrary, format the SD card with a Windows OS utility like SD Card Formatter (5.0.2 developed by Tuxera Inc) in FAT32 format to a size of more than 2GB (at least). Then you can directly copy the files from thepackage_output_hw/sd_cardfolder. The reason is that with thesd_card.imgfile, the VCK190 sometimes does not boot for this particular design. -
At the prompt on UART terminal digit, insert the
petalinuxusername and choose a password (for example,root).
As already stated in the previous subsection, the Thin Platform has several advantages, being based on makefile flow, including ease of use, and fast compilation time. In this separate section, you will design the same project of section 3 Decimation FIR Filter DSP Design, that is, a decimation-by-2 FIR filter taken from the Vitis DSP Library for AI Engine. This time, you will implement such a design into the Thin Platform makefile based template as an alternative to using the two flows described in subsection 3.1 (GUI-based flow) and 3.2 (Makefile-based flow).
The prepare_thin-plat_files.sh script called from within run_all.sh script copies the Thin Platform folder and renames it into thin-plat. It then removes folders (ip/counter, ip/mm2s_vadd_s, ip/s2mm_vadd_s, ip/subtractor) that are not required for this FIR filter design. It then changes other files, as explained in the next section.
cd <WRK_DIR> #your working directory
cd 02-AIE_DSP_with_Makefile_and_GUI/files #current dir
# set your environment
#source files/scripts/<YOUR_OWN>_sample_env_setup.sh
# source run_all.#
source ./scripts/prepare_thin-plat-files.shThe original Thin Platform has the following subfolders:

while this project requires the following folders:

therefore you should have to do manually the following changes:
- Add your AI Engine graph and kernels code into the
vitis/ip/aiefolder and adapt the relatedvitis/ip/aie/Makefileto your case. - Add your HLS kernels code into the
vitis/ipfolder, one HLS kernel in each subfolder, for example,vitis/ip/mm2s_aieandvitis/ip/s2mm_aie. Then check or adapt the relatedvitis/ip/mm2s_aie/Makefileandvitis/ip/s2mm_aie/Makefile. - Add your PS code into the
ps_apps/linuxfolder. For example,ps_apps/linux/aie_test. Then check or adapt the relatedps_apps/linux/aie_test/Makefile. - Adapt the
vitis/src/system.cfgconfiguration file for the Vitis Linker according to your connectivity (in this specific case, it is the same as the original Thin Platform repository, so no changes at all). - Do not modify the
vitis/ip/Makefilesbecause it orchestrates all the Makefiles of the various subfolders. The remaining ones are managed "automatically" by the other Makefiles of the Thin Platform project.
To provide ease, all above steps are already done by the script prepare_thin-plat_files.sh and the Makefiles are already changed and available in this repository.
Run the following commands:
cd <WRK_DIR> #your working directory
cd 02-AIE_DSP_with_Makefile_and_GUI/files #cur dir
# set your environment
#source files/scripts/<YOUR_OWN>_sample_env_setup.sh
#prepare the Thin Platform folder
source ./scripts/prepare_thin-plat_files.shNow you can build the SD card with the following commands:
cd <WRK_DIR> #your working directory
cd 02-AIE_DSP_with_Makefile_and_GUI/files
# set your environment
#source files/scripts/<YOUR_OWN>_sample_env_setup.sh
cd thin-plat
make all TARGET=hwAs already mentioned in the previous subsection, do not use the sd_card.img file generated in the package_output_hw directly. On the contrary, just format the SD card with a Windows OS utility like SD Card Formatter (5.0.2 developed by Tuxera Inc) in FAT32 to a size of more than 2GB (at least) as illustrated in Figure 4.2.1-1. Then you can directly copy the files from the package_output_hw/sd_card folder, as illustrated in Figure 4.2.1-2.
(Figure 4.2.1-1) FAT32 formatting to prepare the sd card for VCK190.
(Figure 4.2.1-2) Copy the files on sd card to boot the VCK190.
At the prompt on UART terminal digit, insert the petalinux username and choose a password to login. For example, root. You should see the following:
versal-rootfs-common-20231 login: petalinux
You are required to change your password immediately (administrator enforced).
New password:
Retype new password:
versal-rootfs-common-20231:~$ sudo su
We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
