ARM enables autonomous vehicles with safety processor

Sep 20, 2016

ARM has launched a new real-time processor with advanced safety features for autonomous vehicles and medical and industrial robots. The ARMCortex-R52 was designed to address functional safety in systems that must comply with ISO 26262 ASIL D and IEC 61508 SIL 3, the most stringent safety standards in the automotive and industrial markets.

The Cortex-R52 is suited for systems that demand advanced safety features alongside efficient and responsive execution, according to its manufacturer. It will enable applications as diverse as surgical automation, safety management and automotive powertrain control. STMicroelectronics is the first ARM partner to announce it has licensed the processor to enable it to create highly integrated SoCs for the automotive market.               Press Image                                                                            "The Cortex-R52 is the first processor built on the ARMv8-R architecture and it was designed from the ground up to address functional safety,” said James McNiven, general manager for CPU and media processing groups, ARM. “We are helping partners to meet particular market opportunities, especially in fully autonomous vehicles and robotics systems where specific functionality is required for safety-critical tasks. By documenting the strict development process, fault modelling and supporting software isolation, ARM is enabling a faster route to market for partners addressing these applications.”

The Cortex-R52 offers hardware-enforced separation of software tasks to ensure safety-critical code is fully isolated. This allows the hardware to be managed by a software hypervisor policing the execution and resourcing of tasks. By enabling the precise and robust separation of software, the Cortex-R52 decreases the amount of code that must be safety-certified, which speeds development and eases software integration, maintenance and validation. The processor also deals with increased software complexity while delivering the determinism and fast-context switching that real-time systems demand.

“The Cortex-R52 supports our Smart Driving vision by enabling a new range of high-performance, power-efficient SoCs for any in-vehicle application demanding real-time operation and the highest levels of functional safety, including powertrain, chassis and ADAS,” said Fabio Marchiò, Automotive & Discrete Group vice president and Automotive Digital Division general manager, STMicroelectronics. “The Cortex-R52’s ability to compartmentalize software provides our users with the best solution for safety without loss of determinism. Its virtualization support simplifies the consolidation of applications and functions into a single processor, delivering a shorter integration time.”
