1 Overview
The primary goal of this Design is to demonstrate the capabilities of VCU hard block present in Zynq UltraScale+ EV devices. The TRD will serve as a platform to tune the performance parameters of VCU and arrive at optimal configurations for encoder and decoder blocks with the streaming use case where bandwidth plays a vital role.
This design supports the following video interfaces:

1.2 Run Flow
The TRD package is released with the source code, Vivado project, Petalinux BSP, and SD card image that enables the user to run the demonstration. It also includes the binaries necessary to configure and boot the ZCU106 board. Prior to running the steps mentioned in this wiki page, download the TRD package and extract its contents to a directory referred to as TRD_HOME which is the home directory.
Refer Section 4.1 : Download the TRD of Zynq UltraScale+ MPSoC VCU TRD 2020.1 wiki page to download all TRD contents.
TRD package contents specific to SDI Video Display design is placed in the following directory structure. The user needs to copy all the files from the $TRD_HOME/images/vcu_sditx/ to FAT32 formatted SD card directory.
