Automotive

Scalability

From parking sensor to cockpit

Arm-based processors scale from the smallest, lowest-cost ultrasonic parking sensors to the server-class compute platforms that enable autonomous vehicles.

Energy Efficiency

Minimum heat, maximum range

Every watt of power a car uses contributes to CO2 emissions and reduces fuel economy. In a fully electric car, power-efficient electronics increase driving range.

Trust

Electronic counter measures thwart attacks

Cyber attacks on cars are a growing and disconcerting trend, compounded by the sheer number of potential points of possible attack — making secure electronics vital.

Safety

Safe, reliable electronics

All of Arm's automotive-related IP is available with a comprehensive functional safety package that accelerates the safety aspects of a complete chip design.

Seamless Scalability

Software Reuse
For driving innovation

The car is the most complex electronic device many of us will buy, with over 100 ECUs soon to become the norm for most vehicles. Over 85% of infotainment systems and many under-the-hood applications are built with Arm-based chips. A common architecture across all electronics, combined with a leading tools ecosystem, enables carmakers and their suppliers to rapidly innovate hardware and software.

Arm partners design technology for the high-performance compute and network platforms that enable advanced driver assistance and autonomous operation. Advanced display and augmented vision technologies, which evolve from mobile technologies, will also become ever more prevalent for enhanced driver-vehicle interaction.

Power Efficiency

Low Energy

Automotive engineers care about two critical aspects of energy consumption: thermal management and efficiency. Chips that control vehicle operations are often deeply embedded into areas that are difficult and costly to cool down. Arm technology delivers high performance computing within tight thermal constraints.

The growing move to increased vehicle electrification means that electrical energy — in both hybrid and fully electric cars — has a much more direct impact on driving range and CO2 emissions than ever before. Arm’s power-efficient heritage and continued focus on the best possible performance per watt are crucial elements that enable automakers to design vehicles that operate reliably, safely, and economically under even the most adverse conditions.

Trust
Connectivity requires security

There are many reasons why improving automotive security has become extremely urgent, such as to prevent theft through the hacking of keyless entry systems and vehicle immobilizer systems. Preventing unauthorized vehicle tracking and remote hacking, especially while the vehicle is being driven, has also become a critical concern.

Arm’s experience in enabling strong security, through technologies such as TrustZone and CryptoCell in payment and content protection, gives the auto industry the opportunity to deploy proven solutions reliably and at scale without having to reinvent them.

Arm’s Inclusive Approach

Safety Matters
Smoothing the path to right-sized functional safety support

Because faults and failures in automotive systems might be life threatening, initial auto industry applications of Arm processors have improved safety in areas such as anti-lock braking systems (ABS) and airbags.

Advanced Driver Assistance Systems (ADAS) and automated driving systems must now be both safe and reliable. Standards and processes were developed to ensure that safety electronics continue to operate in a safe manner even when faults occur.

Arm is at the forefront of developing processor technology that supports functional safety within the ISO26262 international standard.
