CPU32 cores (2 × 16) + 4 lockstep real-time cores per module
AI throughput10,000 TOPS total (2 × 5,000, INT8 / FP4 sparse)
Memory2 × 128 GB LPDDR6, 600 GB/s per module
Power draw200 W compute; ≈ 0.3 kW with 8 cameras, 3 lidars and 2 radars — 0.6% of the stacker’s ≈ 55 kW average draw
Process node2 nm-class SoCs; safety controller on a mature 16 nm node, 15-year supply. Compute is a line-replaceable unit, swapped at mid-life of the stacker’s 15 years
RedundancyEvery sensor is wired to both modules. Module 1 is primary for the boom and spreader and hot standby for the travel path; module 2 is primary for the travel path and people and hot standby for the boom. Module 2 runs a different people-and-obstacle model, so the two never share a blind spot. Either one alone runs the stacker at reduced speed; losing both halts it with the load held.
SafetyThe SIL 3 controller has its own sensors: boom-angle and extension encoders, load cells on the spreader and lift cylinders, a chassis tilt sensor, twist-lock limit switches and safety-rated lidar and radar front and rear. It computes the tip-over envelope at 100 Hz and can stop or lower on its own. A software fault can never drive the reach stacker outside its certified safe envelope.
