Ambarella, Inc., a developer of low-power, HD and Ultra HD video processing semiconductors, has introduced the CV2 camera SoC combining advanced computer vision, image processing, 4Kp60 video encoding, and stereovision in a single chip.
CV2 targets advanced automotive, IP security, drone, and robotic applications, delivering up to 20 times the deep neural network performance of Ambarella’s first generation CV1 chip.
In automotive applications, such as ADAS and self‐driving systems, its ability to run multiple algorithms simultaneously delivers higher perception accuracy and reduces the total number of chips required.
In IP security cameras it enables advanced computer vision in the camera rather than in the cloud, enabling faster response time, lower network utilisation and more accurate classification of objects, people and vehicles.

Fabricated in advanced 10nm process technology, CV2 offers extremely low power consumption. “With CV2 we have dramatically increased our computer vision performance and combined it with full SoC functionality,” said Fermi Wang, CEO of Ambarella.
“As the highest performance member of our new CVflow family, CV2 delivers both the deep neural network and stereovision processing required for the most advanced automotive and security cameras.”
Long-range object recognition
The CV2’s CVflow architecture provides computer vision processing up to 4K or 8‐Megapixel resolution, to enable object recognition and perception over long distances and with high accuracy.
Its stereovision processing provides the ability to detect generic objects without training in ADAS and autonomous vehicle applications. Advanced image processing with HDR (high dynamic range) processing delivers outstanding imaging even in low light and from high-contrast scenes.A complete set of tools is provided to help customers easily port their own neural networks onto the CV2 SoC
Efficient video encoding
Its highly efficient 4Kp60 AVC and HEVC video encoding supports the addition of video recording to automotive ADAS and self‐driving systems and enables the design of both multi‐stream and multi‐imager IP security cameras. CV2 includes a full suite of advanced security features to prevent hacking, including secure boot, TrustZone and I/O virtualisation.
A complete set of tools is provided to help customers easily port their own neural networks onto the CV2 SoC. This includes compiler, debugger and support for industry standard training tools including Caffe and TensorFlow, with extensive guidelines for CNN (convolutional neural network) performance optimisations.
