Ambarella, an artificial intelligence vision silicon chip company, announced the launch of cv22fs and cv2fs car camera system chips (SOC), which are equipped with cvflow artificial intelligence processing technology and comply with ASIL B standards, and can be used for safety critical applications, foreign media reported. Both chips are designed for front-end single and stereo vision ADAS cameras, as well as computer vision electronic control unit (ECU) for L2 + and higher-level automatic driving. AMBA said that the power consumption of cv22fs and cv2fs is extremely low, which enables the primary suppliers and OEMs to meet the performance requirements of NCAP under the power consumption constraints of single box and front ADAS sensor installed on the windshield. Other potential applications of such processors include electronic rear-view mirrors with blind spot detection (BSD), in vehicle driver and cabin surveillance cameras, and look around monitors (AVM) with parking aid. The above two new system chips are the latest products of AMBA cvflow SOC series, which can provide an open platform for automobile OEMs, first-class suppliers and software development partners to develop differentiated and high-performance automobile systems. AMBA explained that the cvflow architecture of cv22fs and cv2fs provides 8 megapixel or higher resolution computer vision processing function at the speed of 80 frames per second for long-distance and high-precision target recognition. Each system chip includes a dense optical flow accelerator for simultaneous location and map building (SLAM) and distance and depth estimation. Multi channel high-speed sensor input and anba's image signal processing (ISP) channel provide necessary support for camera input. It is reported that cv2fs can achieve advanced stereo vision application by adding a dense parallax engine even under challenging lighting conditions. AMBA plans to provide cv22fs and cv2fs samples to customers in the first half of 2020. The key features of cv22fs and cv2fs system chips include: 1. Cvflow architecture supporting deep neural network (DNN); 2. 4-core 1GHz secure cortex ® - A53 processor with secure DSP (digital signal processor) expander and FPU (floating-point unit); 3. Security island with dual core lock step (DCLS) arm ® R52 for asil-c; 4. Dense optical flow engine; 5 Dense stereo parallax engine (cv2fs only); 6. ASIL B functional security level; 7. High speed slvs / Mipi csi-2 / lvcmos interface; 8. Multi channel ISP, with input pixel rate up to 480 megapixel / S; 9. Native support for rggb, RCCB, RCCC, rgb-ir and monochrome sensor formats; 10. Multi exposure high dynamic range (HDR) processing and led flicker suppression; 11 Real time hardware accelerates fish eye shadow correction and lens distortion correction (LDC) 12 and 4 megabytes AVC encoding for video recording and wireless video streaming; 13, a rich set of interfaces, including CAN FD, Gigabit Ethernet, USB 2 host and device, SDXC dual SD card controller, MIPI DSI/CSI-2 4-channel output; 14. Advanced security functions, including OTP, TrustZone ® and IO virtualization for safe startup; 15. Aec-q100 Level 2 (- 40 ℃ to + 125 ℃ (TJ) operating temperature); 16. 10 nanometer process technology.
