Autonomous vehicles rely on a variety of sensors and cameras to perceive their surroundings and navigate without human input. Powering these advanced driver-assistance systems and enabling autonomous driving requires specialized computer hardware capable of processing massive amounts of sensor data in real-time. Some of the key hardware components required include:

Cameras - High resolution cameras are used for computer vision tasks like detecting lane lines, traffic signs, pedestrians and other objects. Advanced image processing requires huge computational power.

Radar - Radar sensors detect objects and their distances. Autonomous Vehicle Chips data for functions like adaptive cruise control. Processing radar signals is a computationally intensive job.

Lidar - Lidar sensors map out the vehicle's environment with laser beams. They construct high definition 3D maps in real-time needed for autonomous navigation. Lidar point cloud data produces massive data loads.

Sensors - Additional sensors track wheel speeds, steering angles, acceleration and other vehicle dynamics. Sensor fusion algorithms combine data from all sources to recognize the driving scene.

Centralized Computing - A centralized computer system with powerful multiprocessor chips is needed to fuse data from all sensors, run AI/deep learning algorithms and control the vehicle's movements autonomously.

Specialized Computer Autonomous Vehicle Chips for Self-Driving

Meeting the high performance requirements of autonomous vehicles requires specialized silicon designed specifically for ADAS and autonomous functions. Mainstream consumer chips lack the parallel processing capabilities, memory bandwidth, and other architectural features needed for real-time sensor analytics and control systems. Some of the customized chips developed for autonomous applications include:

Nvidia Drive - Nvidia's automotive system-on-chips offer powerful graphics processing capabilities re-purposed for neural network processing and sensor fusion. Models like the Orin and Xavier are optimized for deep learning and autonomous driving workloads.

Mobileye EyeQ - Intel-owned Mobileye manufactures ASICs and specialized CPU+GPU systems designed specifically for advanced driver assistance systems. Their EyeQ family powers systems from several automakers.

Tesla FSD Chip - For its full self-driving computer, Tesla designed an in-house system-on-chip with over 36 billion transistors featuring a massive neural network accelerators array. It delivers over 260 TOPS of processing power.

Qualcomm Snapdragon Ride - Built on the Snapdragon platform, Qualcomm's Ride system-on-modules are automotive grade solutions targeting diverse ADAS and self-driving applications.

NXP S32V - Featuring vector processing units, the S32V family from NXP provides high performance for vision, radar and sensor data processing in autonomous platforms.

Ambarella H22 Surround View System - This best-in-class image processing SoC handles 360-degree multi-camera computer vision for advanced driver monitoring systems.

Hardware Accelerators for Autonomous Vehicle Chips

Enabling autonomous functionality through computer vision and deep learning requires massive parallel processing capabilities. Contemporary GPUs have proven very effective at neural network training but self-driving cars need dedicated hardware accelerators optimized for real-time inference. Leading automotive chips employ:

Tensor Cores - Nvidia's Tensor Cores provide up to 140x faster processing of deep learning workloads compared to CPUs alone. They handle sensor analytics and object recognition with ultra-low latency.

Vector Processors - Building vision and lidar data analytics directly into vector processors, as with NXP's S32V, allows tremendous throughput with fine-grained parallelism.

Neural Network Processors - Tesla's FSD chip contains over 300 dedicated neural network cores delivering 260 TOPS to power complex computer vision models instantly.

Vision Processing Units - Ambarella's H22 vision SoC features dedicated vision ISPs and a powerful VPU for advanced 360-degree surround view processing and computer vision functions.

Hardware accelerated deep learning is crucial to achieve the inference speeds below 100ms required for reliable autonomous driving perceptions and control systems. Specialized automotive chips deploy cutting-edge AI acceleration architectures.

On-chip Safety Processing

Beyond high performance, autonomous vehicle chips demandASIL functional safety ratings from their computer hardware. Leading automotive chips incorporate:

Fault Monitoring - Dual/triply redundant processors with internal error checking and correction safeguard mission-critical functions.

Safe States - Fail-operational architectures ensure vehicles default to a minimal risk condition if computer faults occur.

Memory Isolation - Separating memory for safety-critical tasks prevents interference and unintended access.

Functional Monitoring - Hardware monitors proper microcontroller execution and triggers safe states if instructions go awry.

On-chip Safety Islands - Isolating safety logic in dedicated silicon areas enhances integrity and prevents software bugs/attacks from affecting safety behavior.

Advanced ECC - Error correcting memory architectures minimize sensor data corruptions from hardware faults or radiation issues.

Meeting ASIL-D ratings through inherent hardware safety mechanisms futureproofs autonomous vehicles for dramatically improved functional safety compared to conventional vehicles reliant on mechanical/hydraulic braking systems alone.

Autonomous vehicle chips depends on powerful specialized computer hardware optimized for sensor fusion, computer vision, deep learning and high-integrity safety control systems. Purpose-built automotive chips like those offered by industry leaders Nvidia, Mobileye, Tesla, Qualcomm and NXP deploy novel architectures for AI acceleration and on-chip functional safety. This new generation of dedicated self-driving silicon represents the "brains" necessary to power autonomous vehicles and enable revolutionary improvements in mobility, productivity and road safety.
