The Zynq® UltraScale+™ MPSoC Video Codec Unit (VCU) Targeted Reference Design (TRD) consists of an embedded video encoding/decoding application that runs on the Processing System (PS). The overall functionality of the TRD is partitioned between the Processing System (PS), Video Codec Unit, and Programmable Logic (PL) for optimal performance. 

The primary goal of this TRD is to demonstrate the capabilities of the VCU core which is an integrated hard block present in Zynq UltraScale+ MPSoC EV devices. The TRD serves as a platform for the user to tune the performance parameters of VCU and arrives at an optimal configuration for encoder and decoder blocks for their specific use case. The TRD uses Vivado IP Integrator (IPI) flow for building the hardware design and Xilinx Yocto PetaLinux flow for software design. It uses Xilinx IPs and software drivers to demonstrate the capabilities of different components.
