Ambarella, Inc., an AI vision silicon company, announced the CV22FS and CV2FS automotive camera system on chips (SoCs) with CVflow AI processing and ASIL B compliance to enable safety-critical applications. Both chips target forward-facing monocular and stereovision ADAS cameras, as well as computer vision ECUs for L2+ and higher levels of autonomy.
Featuring extremely low power consumption, the CV22FS and CV2FS make it possible for tier-1s and OEMs to surpass New Car Assessment Program (NCAP) performance requirements within the power consumption constraints of single-box, windshield-mounted forward ADAS cameras. Other potential applications for the processors include electronic mirrors with blind spot detection (BSD), interior driver and cabin monitoring cameras, and around view monitors (AVM) with parking assist.
Intelligent viewing platforms

The two new SoCs are the latest additions to Ambarella’s successful CVflow SoC family that offers automotive OEMs, tier-1s, and software development partners an open platform for differentiated, high-performance automotive systems. ZF, a global technology tier-1 and supplier of systems for passenger cars and commercial vehicles, is working with Ambarella on viewing and sensing systems:
“ZF is pleased to be working with Ambarella on the next generation of intelligent viewing platforms for Surround View Visualisation, Driver Monitoring stand-alone vision processing, and e-mirror solutions for both the passcar and commercial vehicle markets,” said Aaron Jefferson, vice president of ADAS product planning at ZF. “The CVflow SoCs’ combination of high quality imaging and advanced AI processing enables ZF to offer a wide range of viewing and interior sensing applications.”
Visual perception software
HELLA Aglaia, a global developer of intelligent visual perception software, has worked with Ambarella’s CVflow processors over the past year: “We chose Ambarella’s CVflow SoCs due to their ability to deliver extremely high computer vision processing performance with very low power consumption,” said Kay Talmi, managing director at HELLA Aglaia. “With the introduction of the CV22FS and CV2FS ASIL SoCs, Ambarella now delivers the functional safety features required by automotive OEMs for the mass production of safety-critical systems.”
“Ambarella’s CVFlow architecture delivers an unparalleled combination of AI performance and power efficiency,” said Fermi Wang, president and CEO of Ambarella. “We are pleased to introduce these ASIL compliant CVflow SoCs, delivering on our promises to our partners and customers and further demonstrating our commitment to the automotive market.”
Advanced stereovision applications
Ambarella will also demonstrate a range of applications from other key partners running on the CVflow engine
The CV22FS and CV2FS’s CVflow architecture provides computer vision processing in 8-megapixel or higher resolution at 30 frames per second for object recognition over long distances and with high accuracy. The SoCs each include a dense optical flow accelerator for simultaneous localisation and mapping (SLAM), as well as distance and depth estimation. Multi-channel high-speed sensor input and Ambarella’s image signal processing (ISP) pipeline provide the necessary camera input support, even in challenging lighting conditions. CV2FS also enables advanced stereovision applications by adding a dense disparity engine.
Ambarella will demonstrate its CVflow SoC family during CES 2020 to select customers and partners. Demonstrations will include HELLA Aglaia’s deep learning ADAS algorithms and Ambarella’s EVA (Embedded Vehicle Autonomy) self-driving prototype vehicle. Ambarella will also demonstrate a range of applications from other key partners running on the CVflow engine. CV22FS and CV2FS are scheduled to sample to Ambarella customers in the first half of 2020.
