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:
Sources:- File source (SD card, USB storage, SATA hard disk).
- Stream-In from network or internet.
Sinks:
- SDI-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:
- 1G Ethernet on PS
