Capture Every Mission Critical Frame with PCIe-Based ARINC 818 Frame Grabber:
ARINC 818 Frame Grabber enables reliable, high-speed video capture for modern aerospace and defense systems. Every second, aircraft, defense platforms, and unmanned systems generate vast amounts of high-resolution video from cameras, radar, infrared sensors, and advanced cockpit displays. This real-time data supports mission-critical applications such as navigation, surveillance, target tracking, and situational awareness, where speed, accuracy, and reliability are essential.
This is where ARINC 818-2, the industry standard Avionics Digital Video Bus (ADVB) protocol, plays a key role in enabling reliable transport of uncompressed digital video across avionics systems.
To unlock the full potential of high-speed video streams, PCIe based ARINC 818-2 frame grabbers play an important role. By combining FPGA with a high-speed PCI Express (PCIe) interface, these solutions enable real-time video acquisition, protocol decoding, Direct Memory Access (DMA), recording, visualization, and analysis. The result is faster system integration, improved development efficiency, and reliable performance for Next Gen aerospace and defense applications.
ARINC 818-2: The Trusted Standard for Aerospace Video:
ARINC 818-2 is the latest revision of the ARINC 818 standard, developed for transmitting high speed, uncompressed digital video in commercial and military aircraft. It provides high bandwidth, low latency, and deterministic performance required for mission critical applications, including cockpit displays, cameras, radar systems, infrared sensors, and surveillance platforms.
Built on a Fibre Channel based physical layer, ARINC 818-2 supports data rates from 1.0625 Gbps to 10 Gbps and uses an Interface Control Document (ICD) to define video resolution, pixel format, frame timing, and synchronization. This ensures reliable and consistent communication between connected devices.
As ARINC 818-2 continues to be adopted across modern avionics platforms, native hardware support has become essential for capturing, processing, and analyzing high-speed video streams without compromising performance or introducing additional latency
Why PCIe Matters in ARINC 818-2 Video Acquisition:
Capturing ARINC 818-2 video is only part of the process. The captured data must also be transferred quickly and reliably to the host system for display, recording, or further processing. PCI Express (PCIe) has become the preferred host interface because it provides the speed, bandwidth, and efficiency needed for real-time video applications.
Key benefits of PCIe include:
- High Bandwidth: Supports high-speed transfer of multiple ARINC 818-2 video streams.
- Low Latency: Enables fast and reliable real-time video capture and processing.
- Direct Memory Access (DMA): Transfers video data directly to system memory while reducing CPU usage.
- Easy System Integration: Compatible with COTS servers, rugged mission computers, and embedded systems.
By combining PCIe with FPGA-based ARINC 818-2 processing, Frame Grabbers can efficiently decode, capture, and transfer video streams to the host system. This architecture enables engineers to build reliable, high-performance video acquisition solutions for demanding aerospace and defense applications.
PCIe-Based ARINC 818-2 Frame Grabber Architecture:
A PCIe-based ARINC 818-2 frame grabber is designed to capture, process, and transfer high speed video efficiently. The architecture typically consists of three key functional blocks that work together to ensure reliable real-time video acquisition and data transfer.
1. ARINC 818-2 Physical and Protocol Layer:
An SFP cage (optical or 75-ohm Copper) provides the physical ARINC 818-2 connection. The FPGA implements the Fibre Channel based serial transceiver, frame synchronization, CRC/error checking, and ADVB packet decoding needed to recover raw video data and header information from the incoming bitstream, in line with iWave product description of frame grabber boards that capture video and header data across the PCIe bus.
2. Video Processing and Format Conversion:
Once frames are recovered, on board logic can convert between ARINC 818-2 and standard display formats. Frame grabbers and converter products in this category typically support bidirectional conversion between ARINC 818-2 and HDMI, allowing captured video to be viewed directly on a commercial monitor while the same stream is simultaneously made available to the host PC.
3. PCIe Host Interface and DMA Engine:
A PCIe hard IP core (commonly Gen2/Gen3, x4 or x8 depending on the design) connects the FPGA fabric to the host. A DMA engine streams captured video and metadata into host memory with minimal CPU involvement, and a software development kit typically exposes APIs, sample applications, and driver support so integrators can build acquisition, recording, or analysis software on top of the hardware quickly.
