Getting Started with CIG4-8H
Overview
CIG4-8H GMSL Video Injection Card（Hereinafter referred to as video injection card）is an high-speed image product based on FPGA ,and it independently developed by SZ sensing tech co., Ltd. (for short as SENSING ), a series of SENSING Image Solution.The video injection card adopts PCIe Gen3 technology, which can realize 8-channel video/image injection, and adopts high-precision multi-channel time synchronization technology to ensure that multi-channel data can be synchronized output, and the product is widely used in the hardware-in-the-loop HIL simulation system, digital acquisition and reinjection system, and video simulation system and other scenarios.

After collecting data with autonomous vehicles, algorithm validation and optimization are required, which demands a data injection system. The autonomous driving IPC transmits collected video data from hard disks to the video injection card through the PCIe interface. The card then synchronously outputs 8 channels of video based on timestamps, simulating the camera time sequence and transmitting it to the domain control through the GMSL interface. The CyberCobra card supports gPTP/PTP synchronization, achieving time synchronization through switches, IPC and ACU, ensuring all devices in the system are on the same timeline.
