The coding style in Vivado HLS is quite similar to C++. TCL Script: It contains the commands needed by Vivado HLS to integrate the several components (source code, testbench and other resources), and the stages to perform (synthesis, C simulation, C/RTL co-simulation, RTL export).

Testbench: It is a C++ code which loads the data into the accelerator, executes it and retrieves the data, allowing to compare the results in order to verify if the implementation is correct in C++ and RTL.Р”Р€. Source code: It contains the module (C++ function) of the accelerator and a header which allows to integrate it to other parts, such as the testbench.Р”Сћ. Please, consider that this tutorial is based on Vivado HLS 2018.3, which is backwards compatible.Р”Р„ basic Vivado HLS project is composed of the following components:Р”РЋ.

To build our first Xilinx OpenCV project, we need to know how to integrate it to Vivado HLS. In this wiki, we are going to explore how to use Xilinx OpenCV library in Vivado HLS. That means that xfOpenCV can be used in projects by recognizing the author when distributing the application. Yes, it is! Xilinx OpenCV is completely supported and maintained by the community under the BSD-3 license.

Matrix-matrix operations (addition, weighted-addition)Р”В¬urrently, all the library is intended for Xilinx SDx tool suite, but it is completely possible to integrate Xilinx OpenCV to the Vivado HLS tool for accelerator-oriented projects, which are not based on System-on-Chip (SoC) but in a common FPGA, such as Artix 7 in the PicoEVB, which communicates to a host computer through a PCIe port.

Border and edge detection algorithms (Canny, Sobel).

Inside this function, you might find some common algorithms such as : Have you ever thought in accelerating image processing algorithms in FPGA? Xilinx OpenCV (also known as xfOpenCV ) is a templated-library optimized for FPGA High-Level Synthesis (HLS), allowing to create image processing pipelines easily in the same fashion that you may do it with the well-known OpenCV library.
