The CV3-AD685’s highly efficient CVflow AI neural vector processor (NVP) engine enables high performance, low latency, and low-power NN processing. The NVP is enhanced to efficiently enable the latest advancements in NN inference, including support for transformer networks. Additionally, the CVflow’s general vector processor (GVP) provides traditional computer vision processing while including specific optimization enhancements for HD radar. Twelve Arm Cortex A78AE CPUs and 3 dual-core, lockstep pairs of Cortex-R52 CPUs are included. CV3-AD685 is targeting ASIL-B on the chip level, with an ASIL-D safety island.
The on-chip image signal processor (ISP) provides outstanding imaging in low-light conditions, including high dynamic range (HDR) processing to extract maximum image detail in high-contrast scenes, enhancing the AI and computer vision capabilities of the chip and delivering clear video for viewing. CV3-AD685 also provides high-resolution video recording and streaming at very low bit rates with efficient encoding in the H.265 and H.264 video formats.
The hardware security module (HSM) provides isolation of different domains and secure software provisioning, as well as a suite of advanced cybersecurity features, such as asymmetric/symmetric crypto acceleration, secure storage and key provisioning, encrypted CVflow tasks, true random number generator (TRNG), one-time programmable (OTP) memory, DRAM scrambling and DRAM virtualization.
Fabricated in Samsung’s advanced 5nm automotive process technology, the low power consumption CV3-AD685 SoC is an ideal platform for efficiently implementing assisted and autonomous driving for L2+ to L4 vehicles, multi-sensor ADAS, DMS and OMS in-cabin monitoring systems, multi-channel electronic mirrors with BSD, and intelligent parking assistance and automated parking systems.
