Ambarella announces CV22FS and CV2FS automotive camera SoCs for ADAS
Ambarella 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 advanced driver-assistance systems (ADAS) cameras, as well as computer vision ECUs (electronic control units) for L2+ and higher levels of autonomy. Featuring low power consumption, the CV22FS and CV2FS are designed to be used by Tier 1s and OEMs (original equipment manufacturers) 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.
The two new SoCs are the latest additions to Ambarella’s CVflow SoC family that offers automotive OEMs, Tier 1s, and software development partners an open platform for differentiated, high-performance automotive systems.
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 localization and mapping (SLAM), as well as distance and depth estimation. Multi-channel high-speed sensor input and Ambarella’s image signal processing (ISP) pipeline are intended to 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.
