Zynq UltraScale＋ MPSoC VCU TRD 2018.3 - HDMI Video Capture and HDMI Display With SDSoC
Table of Contents
1 Overview
This design-module demonstrates how to add a data-copy (also known as By-Pass) accelerator between HDMI Video Capture (HDMI-Rx) and HDMI Display (HDMI-Tx) pipelines in PL using SDSoC tool. The accelerator function (which simply copy the input data to output) is translated to RTL using the Vivado HLS compiler (which is part of SDSoC tool).
Sources:
HDMI-Rx capture pipeline implemented in the PL.
File source (SD card, USB storage, SATA hard disk).
Stream-In from network or internet.
Sinks:
HDMI-Tx display pipeline implemented in the PL.
VCU Codec:
Video Encode/Decode capability using VCU hard block in PL
AVC/HEVC encoding.
Encoder/decoder parameter configuration.
Streaming Interfaces:
10G PL Ethernet.
1G Ethernet on PS
