ARM offers functional safety package for ARM® Cortex®-A processors as it broadens its support for automotive
Cambridge, UK, April 23, 2015 – ARM is licensing functional safety support across its Cortex-A, Cortex-R and Cortex-M processor families to deliver even stronger alignment for automotive use as the industry seeks to meet rapidly rising compute demands. This will help the ARM ecosystem shape next generation technologies as vehicle manufacturers plan increasingly complex driver assistance and infotainment systems. ARM-based SoCs are already widely used in the automotive sector.
According to ARM, Advanced Driver Assistance Systems (ADAS) equipped vehicles will require at least 100x more compute performance by 2024 compared to 2016 models, with functional safety an industry priority. By offering the first-ever applications processor functional safety package for partners ARM is helping to enable this vision. Currently, companies must build complete safety cases on a chip-by-chip basis, duplicating effort and increasing industry costs. Greater supply chain efficiency is vital for vehicle makers who must balance increasing compute demands with next generation models but still deliver competitive pricing.
"Exciting new technologies are being deployed by manufacturers to make vehicle intelligence the prime consideration for consumers," said Richard York, vice president of embedded marketing at ARM. "ADAS promises far greater intelligence and road safety, and the efficiency advantages of the ARM ecosystem mean our partners are well-positioned to deliver this technology. Today’s announcement re-affirms our commitment to help shape future automotive markets."
ARM Cortex-A Safety Documents Package
- Support for future Cortex-A processors with initial packages for Cortex-A57, Cortex-A72 and Cortex-A53 processor licensees
- Helps development and safety assessment of SoC designs to help meet the goals of functional safety standards such as ISO 26262 and IEC 61508
- Delivers a safety manual, FMEA report and development interface report
"With an 18 percent unit CAGR, ADAS features are exhibiting the highest growth within the automotive electronics domain as vehicle makers look to differentiate on enhanced product safety," said Chris Webber, vice president of automotive at research firm Strategy Analytics. "These technologies are stepping stones on the road to fully autonomous driving systems which will demand robust functional safety integrated within the control architecture development. This must be coupled with processors capable of higher performance code execution and data throughput."
Increasing Vehicle Compute Performance
The path to high performance, automotive-grade, System on Chips (SoCs) will enable future ADAS based on radar and vision technology and other driver assist and infotainment capabilities.
Today, premium cars have more than 100 processors on board utilizing tens of millions of lines of code. To meet future ADAS demands, ARM expects processor performance compared to 2016 vehicles to increase 20x by 2018, 40-50x by 2020 and 100x by 2024. Meeting this ambition will require deeper functional safety support and higher performance, energy-efficient SoCs.
ARM’s partners are using the latest technology to serve multiple automotive needs such as infotainment as well as ADAS. This includes the Cortex-A53 and Cortex-A57 processors, and ARM partners Freescale® Semiconductor and Texas Instruments have now announced they will adopt ARM’s recently launched Cortex-A72 processors for vehicle SoCs.
Freescale: "ARM’s Cortex-A72 processor technology delivers exceptional power and performance that aligns to Freescale’s strategic vision of scalable solutions for our automotive customers," said Ron Martino, vice president of applications processors and advanced technology adoption, MCU organization at Freescale. "As the world’s top carmakers and their suppliers develop infotainment systems with Freescale’s future i.MX applications processors, the Cortex-A72 cores will play an important role in enabling next generation services and application performance."
Texas Instruments (TI): "Today’s consumers expect their driving experience to be fun with increased connectedness and telematics functionality for entertainment purposes, as well as a higher emphasis on ADAS applications to ensure a safe ride," said Curt Moore, general manager of automotive processors at TI. "As compute performance requirements in infotainment and ADAS applications continue to grow, ARM Cortex-A processors are critical building blocks enabling the next generation driver experience. We are pleased to continue to enable our customers to push the envelope of performance in the ADAS and Infotainment markets through our licensing of the newest ARM Cortex-A72 processor."
