# PYNQ_Projects

This repository is a full step-by-step guide for creating a video processing hardware overlay. All pojects are made in **Vivado 2016.2** and tested on **PYNQ V2.1 image**. All the projects are explained in detail in report.pdf. The user should be able to recreate the projects with this information.
