An automotive RISC-V ADAS platform, safety and AI on one SoC
The ADAS SoC is an automotive-grade RISC-V platform that combines an application compute cluster, a functional-safety island running in lockstep, an on-chip AI engine for perception, and the WIOWIZ sensor-fusion datapath, together with the automotive bus and hardware-security suite. It is architected with ISO 26262 functional safety in mind, so the compute, safety monitoring and perception domains are brought together on a single die as a reference design for next-generation driver assistance.
Architecture
Clean architectural view of the reference SoC. Every block is WIOWIZ RTL on our own RISC-V cores, and internal micro-architecture is not shown.

RISC-V Architecture
Three RISC-V domains work together on the ADAS SoC, an application cluster for compute, a lockstep safety island for ASIL-grade monitoring, and management, alongside an AI perception engine and the sensor-fusion datapath. The compute domain runs the driver assistance software stack, the safety island watches it in lockstep, and the perception and fusion blocks feed a single tracked view of the road into the platform. It is WIOWIZ IP, with no licensed cores anywhere on the die, architected, implemented and verified with our in-house EDA.
Key Features
Three-domain architecture
Application, management and safety domains run side by side with hardware lockstep on the safety island.
On-chip AI perception
An integrated NPU runs perception workloads in hardware, keeping detection on-die and close to the sensors.
Integrated sensor fusion
The WIOWIZ datapath fuses camera, radar and LiDAR into one tracked view of the vehicle surroundings.
Full automotive bus suite
Native CAN-FD, LIN, SENT and TSN Ethernet connect the SoC to the wider vehicle network.
Hardware security module
An on-chip HSM provides secure boot and crypto services to protect the platform and its data.
WIOWIZ IP and VIP
Zero licensed cores, architected, implemented and verified with WIOWIZ EDA.
