Modern embedded systems increasingly require high-resolution video output with low latency and reliable connectivity. From industrial HMIs to medical imaging and digital signage, 4K Ultra HD (UHD) display capabilities have become a key requirement.
HDMI (High-Definition Multimedia Interface) has emerged as a widely adopted standard for delivering uncompressed high-quality video across a broad range of display devices. Leveraging this, iWave Global’s platform based on the AMD Versal AI Edge Gen2 enables efficient implementation of real-time 4K video capture, processing, and display pipelines.

HDMI for 4K Ultra HD Display
HDMI enables the transmission of uncompressed digital video over a single interface, simplifying system design while ensuring compatibility across commercial and industrial displays.
On iWave’s Versal AI Edge Gen2 system on modules, HDMI interfaces support both 4K input and output, enabling seamless video capture and display. The platform is designed to handle high data bandwidth requirements while maintaining signal integrity, ensuring stable and reliable performance. Key capabilities include support for resolutions up to 4K@60 (3840 × 2160), embedded synchronization, and compatibility with a wide range of display devices.
Versal AI Edge Gen2 System on Module Overview
The AMD Versal AI Edge Gen2 integrates multiple processing domains that make it well suited for video pipeline implementation.
The programmable logic (PL) enables real-time video processing, while the processing system (PS), based on Arm Cortex cores, manages system control and configuration. High-speed memory interfaces support efficient frame buffering, and integrated high-speed transceivers enable reliable display connectivity.
This heterogeneous architecture allows developers to build flexible and scalable video pipelines tailored to specific application requirements.
4K HDMI Video Pipeline Architecture
A typical 4K HDMI pipeline on the platform consists of multiple stages working together to process and display video in real time.

- HDMI Input Capture: Incoming 4K video streams are received through the HDMI interface and decoded into pixel data streams for further processing.
- Video Processing in Programmable Logic: The FPGA fabric performs real-time operations such as resolution scaling, color space conversion, and frame timing adjustments. These operations are implemented in hardware, ensuring deterministic and low-latency processing.
- Frame Buffering: Processed frames are stored in internal memory such as DDR or LPDDR. This enables smooth playback, frame synchronization, and multi-buffering for continuous video streaming.
- System Control: The processing system configures HDMI interfaces, manages memory buffers, and controls the overall pipeline operation.
- HDMI Output: The final processed video is transmitted to external displays in 4K UHD resolution, ensuring high-quality visual output.
