Introduction
Version: Vitis 2022.2
Xilinx FPGAs and Versal ACAP devices are uniquely suitable for low-latency acceleration of high performance algorithms and workloads. With the demise of traditional Moore’s Law scaling, design-specific architectures(DSAs) are becoming the tool of choice for developers needing the optimal balance of capability, power, latency, and flexibility. But, approaching FPGA and ACAP development from a purely software background can seem daunting.
With this set of documentation and tutorials, our goal is to provide you with an easy-to-follow, guided introduction to accelerating applications with Xilinx technology. We will begin from the first principles of acceleration: understanding the fundamental architectural approaches, identifying suitable code for acceleration, and interacting with the software APIs for managing memory and interacting with the target device in an optimal way.
This set of documents is intended for use by software developers, it is not a low-level hardware developer’s guide. The topics of RTL coding, low-level FPGA architecture, high-level synthesis optimization, and so on are covered elsewhere in other Xilinx documents. Our goal here is to get you up and running with Vitis quickly, with the confidence to approach your own acceleration goals and grow your familiarity and skill with Xilinx over time.
Provided Design Files
In this directory tree you will find a collection of documents and a directory named design_source
.
The design_source
directory contains all of the design elements - hardware and software - for the
tutorial you’re currently reading. The example applications correspond to specific sections in the guide.
Every effort has been made to keep the code samples as concise and “to the point” as possible.
Build the Software and Hardware
Attached Makefile
can be used to build the design:
Command | Run Result |
---|---|
make run TARGET=sw_emu |
Build and run Software Emulation |
make run TARGET=hw_emu |
Build and run Hardware Emulation |
make run TARGET=hw |
Build and run the application on Hardware |
The above Makefile flow would need PLATFORM
and PLATFORM_REPO_PATH
export PLATFORM=xilinx_u250_gen3x16_xdma_4_1_202210_1 # Example to set the PLATFORM before launching the run
export PLATFORM_REPO_PATH=/opt/xilinx/platforms/ # Example to set the PLATFORM_REPO_PATH before launching the run
This tutorial uses OpenCV for the application, please set the OpenCV env
variable as below
export OPENCV_INCLUDE=<path>/opencv-4.4.0/include
export OPENCV_LIB=<path>/opencv-4.4.0/lib
export LD_LIBRARY_PATH=<path>/opencv-4.4.0/lib:$LD_LIBRARY_PATH
Once the build is complited, a folder build
under directory design_source
will contain all the executables and alveo_example.xclbin to run the tutorial
Note: The hw_emu
is not tested for this release.
