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.
This design supports the following video interfaces:
Sources:
- Test pattern generator (TPG) implemented in the PL.
- HDMI-Rx capture pipeline implemented in the PL.
- MIPI CSI-2 Rx capture pipeline implemented in the PL.
- File source (SD card, USB storage, SATA hard disk).
- Stream-In from network or internet.
Sinks:
- DP Tx display pipeline in the PS.
- 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.
- Demonstrate the multi-stream capability of VCU at 4k 60 Hz throughput
Streaming Interfaces:
- 1G Ethernet PS GEM
Video format:
- NV12
The below figure shows the TRD block diagram.
- Demonstrate the multi-stream capability of VCU at 4k 60 Hz throughput.
- Supports 2-4KP30 multi-stream feature with any 2 of HDMI-Rx, TPG, and MIPI as the input source and HDMI-Tx as display pipeline.
- Supports 4-1080p60 multi-stream feature with 3 HDMI-Rx and 1 MIPI as the input source and HDMI-Tx as display pipeline.
- Supports 8-1080p30 multi-stream feature with 7 HDMI-Rx and 1 MIPI as the input source and HDMI-Tx as display pipeline.
Other features:
- This design supports 8 channel memory based SCD(Scene Change Detection) IP. SCD can be enabled or disabled through configuration

The below table gives information about the features supported in this design.
| Pipeline | Input source | Output Type | Resolution | VCU codec |
|---|---|---|---|---|
Capture--> Display(Passthrough pipeline) | HDMI-Rx/MIPI/TPG | HDMI-Tx/DP | 4KP/1080p | None |
Single Stream: Capture--> SCD --> Encode--> Decode--> Display | HDMI-Rx/MIPI/TPG | HDMI-Tx/DP | 4KP/1080p | HEVC/AVC |
Multi-Stream (2 input sources): Capture--> SCD --> Encode--> Decode--> Display | HDMI-Rx/MIPI/TPG | HDMI-Tx | 4KP30 | HEVC/AVC |
Multi-Stream(4 input sources): Capture--> SCD --> Encode--> Decode--> Display | HDMI-Rx/MIPI/TPG | HDMI-Tx | 1080P60 | HEVC/AVC |
| Multi-Stream(8 input sources): Capture--> SCD --> Encode--> Decode--> Display | 7-HDMI-Rx + 1 MIPI | HDMI-Tx | 1080P30 | HEVC/AVC |
Single Stream: Record/Stream-Out pipeline | HDMI-Rx/MIPI/TPG | File Sink/ Stream-Out | 4K/1080p | HEVC/AVC |
Multi-Stream(2 or 4 i/p sources): Record/Stream-Out pipeline | HDMI-Rx/MIPI/TPG | File Sink/ Stream-Out | 2-4KP30/4-1080p60 | HEVC/AVC |
Multi-Stream(8 input sources): Record/Stream-Out pipeline | 7-HDMI-Rx + 1 MIPI | File Sink/ Stream-Out | 8-1080P30 | HEVC/AVC |
File/Streaming Playback pipeline | File Source/ Stream-In | HDMI-Tx/DP | 4K/1080p | HEVC/AVC |
NOTE: DP will support a max resolution of 4KP30
TPG will not support 1080P30 resolution mode.
