Raw sensors in, driving decision out, on one die
The Sensor Fusion SoC takes raw camera, radar and LiDAR streams and turns them into a driving decision entirely on-chip. Each sensor is processed in dedicated hardware, time-aligned, and fused into a single tracked view of the world, then a hardware decision engine emits the control output. There is no application processor in the loop, and no licensed third-party cores anywhere on the die.
Architecture
Clean architectural view. Every block is WIOWIZ RTL on our own RISC-V core, and internal micro-architecture is not shown.

RISC-V Architecture
A RISC-V management core orchestrates the SoC, bringing up the pipeline at boot, loading calibration, parsing incoming sensor packets and servicing interrupts, while the heavy perception and fusion run in dedicated datapaths alongside it. The design is pure-digital and built on WIOWIZ's own RISC-V core, keeping the silicon licence-free and fully controllable from spec to sign-off with our in-house EDA.
Key Features
Raw sensor → decision
The full pipeline from sensor input to control output runs on one die, no host CPU in the loop.
Hardware time sync
Per-sensor timestamping aligns camera, radar and LiDAR and flags stale inputs before they mislead the fuser.
On-die AI perception
An INT8 CNN engine runs object detection at frame rate directly in hardware.
All-weather radar
A dedicated radar DSP path adds range and Doppler detection when vision degrades.
Multi-object tracking
Kalman tracking over a bird's-eye-view occupancy grid maintains one fused world model.
WIOWIZ IP and VIP
Zero licensed cores, architected, implemented and verified with WIOWIZ EDA.
