In the realm of automotive video applications, the Gigabit Multimedia Serial Link (GMSL) serial interface, pioneered by Maxim Integrated, has emerged as a high-speed solution. This interface finds its primary applications in automotive video systems, including infotainment and advanced driver assistance systems (ADAS). Its versatility extends to use in robotic and intelligent traffic applications.
GMSL Camera Interface Components
The GMSL camera interface comprises serializer and deserializer families equipped with various interfaces like HDMI, CSI-2, DSI, asymmetric DSI, eDP, oLDI, and single, dual, and quad GMSL1/GMSL2. These interfaces can handle input or output across a single cable reaching up to 15 meters, using either coaxial or shielded twisted pair cables. Serialization transforms data into a serial stream on the transmitting end, while deserialization converts it into a parallel word for processing on the receiving end.
Key Features of GMSL Cameras
GMSL cameras are integral to industrial applications requiring high data rates and long-distance support. Notably, their ability to transmit data instantly in challenging industrial conditions, with zero latency, sets them apart. Additional features include virtual camera support, backward compatibility, automatic repeat request functionality, and compatibility with ARM platforms.
Applications of GMSL in Embedded Vision
1. Vehicle Infotainment Systems: GMSL is the preferred choice for automotive infotainment systems, facilitating passenger entertainment, display of vehicle information, navigation, and connectivity. Its application extends to inspection cameras and street lighting cameras.
2. Advanced Driver Assistance Systems (ADAS): GMSL SerDes technology meets the essential needs of ADAS systems, ensuring high reliability and flexibility for transmitting uncompressed camera feeds.
3. Robotics: In autonomous mobile robots (AMR), GMSL cameras play a crucial role in navigation, object detection, and identification due to their fast frame rates and low exposure time capabilities. They can transmit data up to 15 meters, making them suitable for remote robotics.
4. Intelligent Transportation Systems: Smart traffic systems leverage GMSL's ability to transmit captured image and video data over long distances using sensors, cameras, and routers.
5. Fleet Administration: Fleet management systems, particularly in large vehicles like trucks and forklifts, benefit from GMSL interfaces. They enable the deployment of multi-camera surround-view systems, addressing blind spots and enhancing driver awareness.
