Neural Processing Unit (NPU)
A specialized processor designed to accelerate artificial intelligence tasks in vehicles.
A Neural Processing Unit (NPU) is a specialized microprocessor designed to accelerate artificial intelligence (AI) and machine learning (ML) tasks, particularly deep neural network computations. Unlike traditional CPUs or GPUs, NPUs are optimized for parallel matrix and tensor operations commonly used in neural network inference and training.
In the automotive industry, NPUs are integrated into advanced ADAS (Advanced Driver Assistance Systems) and autonomous driving platforms to handle real-time data from cameras, LiDAR, radar, and other sensors. They enable low-latency object detection, path prediction, and decision-making, ensuring fast and power-efficient AI computation directly within the vehicle.
Modern vehicle domain controllers or system-on-chips (SoCs) often include NPUs alongside CPUs and GPUs to create a heterogeneous computing environment, balancing performance, efficiency, and thermal management.
