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.

Information

Each project is documented in report.pdf. All the HLS, bit, tcl and notebook files can be found in the sub-directory. These can be easily imported onto your own PYNQ device.

Project list

All projects are explained in <report.pdf>. and chapter number is in the title.

- Rebuilding the PYNQ base overlay [2.2]
