Introduction

This application note describes how to run video loopback design using the PolarFire® Video Kit with a video source, display, High-Definition Multimedia Interface Transmitter (HDMI TX) port, and High-Definition Multimedia Interface Receiver (HDMI RX) port. The demo design features a fully-integrated solution developed using Microchip's Libero® System-on-Chip (SoC) software that enables you to evaluate PolarFire FPGA in smart embedded vision applications and to build prototypes, quickly. The design is capable of dynamically supporting video resolutions from 720p@30 fps to 4K@60 fps. For more information about Smart Embedded Vision IPs, see Smart Embedded Vision. 

The demo design captures the video and audio from a source using the HDMI 2.0 RX port and decodes the HDMI data as a video and audio data. The decoded data is then written to the FIFOs before looping back to an external HDMI complaint source or a monitor using the HDMI 2.0 TX port.
