ARM has launched an all-new safety processor called the ARM Cortex-R52 that comes with advanced safety features. The same has been built from the ground up for use in autonomous vehicles and for medical and industrial robots.
The
ARM Cortex-R52 core focus is safety and with that comes compliance for ISO
26262 ASIL D and IEC 61508 SIL 3, the most stringent safety standards in the
automotive and industrial markets. It is a real-time processor that should
enable applications as critical as surgical automation and even for safety
management in automotive powertrain control.
STMicroelectronics
is the first ARM partner to announce it has licensed the high performance
processor to enable it to create highly integrated SoCs for the automotive
market.
“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.”
Offering
hardware-enforced separation of software tasks, the Cortex-R52 ensures
safety-critical code is fully isolated. With the code now isolated, the
hardware can now be managed by a software hypervisor. By enabling the precise
and robust separation of software, the Cortex-R52 decreases the amount of code
that must be safety-certified, so speeding up development as software
integration, maintenance and validation is easier.
“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
DENSO,
a leading global supplier of advanced automotive technology, systems and
components is supporting the launch.
The company's Cortex-R52 targets markets where safety is critical, including autonomous vehicles, robotics and health care.
ARM
is looking to establish itself in the burgeoning autonomous car market with a
new chip design that is aimed at addressing the high safety standards needed
for not only driverless vehicles but also other areas such as industrial and
medical robots.
Company
officials on Sept. 20 unveiled the Cortex-R52, a system-on-a-chip (SoC) design
built on the company's ARMv8-R architecture that is designed to comply with a
range of safety standards—such as ISO 26262 ASIL D and IEC 61508 SIL 3—that
apply to situations in the growing internet of things (IoT), such as autonomous
cars and robots in health care settings, where safety and security is paramount
in the interaction between humans and machines.
The
includes with robots that assist doctors in surgery to self-driving cars that
need to understand the environment around them and immediately react to ensure
the safety of the drivers and the people around the cars. In addition, the
systems need to be highly secure to protect them against hackers.
"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," James McNiven, general manager for
CPU and media processing groups at ARM, said in a statement.

Like
other chip companies, ARM—which is being bought by Softbank for $32.2
billion—is working to branch out beyond its core markets to gain traction in a
broad range of emerging growth areas being fueled by the rapid proliferation of
connected devices, systems and sensors that make up the growing IoT. ARM
designs SoCs and licenses those designs to a wide variety of chip
manufacturers, such as Qualcomm, Samsung and Applied Micro. Most smartphones
and tablets run on ARM-designed processors, but now company officials are
looking to extend the reach of the architecture into other areas, from the data
center to the IoT.
A
growing number of ARM chip partners—including Qualcomm and Broadcom—are rolling
out new products for the autonomous vehicle space. ARM also has been building
up its capabilities in the IoT, including with the acquisition last year of
Offspark, a company that specialized in security software for connected devices
and sensors.
In
a post on the company blog, James Scobie, a product manager at ARM, wrote about
the growing demand for safety and security in IoT systems.
"Across
multiple markets, electronic systems are becoming more complex—including
automotive, industrial control and healthcare," Scobie wrote.
"Vehicles are beginning to drive themselves, industrial robots are
becoming increasingly collaborative, and medical systems are automated to
assist with surgery or deliver medication. More of these systems are demanding
functionally safe operation and requiring that functional safety be provided at
a higher safety level than previous generations of systems demanded."
The
Cortex-R52 architecture was created to address those functional safety needs,
not only in self-driving cars, but also in increasingly automated factories
that include autonomous robots that use machine learning and vision systems to
enable them to work with less human control, he wrote.
"Outside
the factory, robotics will be used in environments too harsh for humans, such
as the nuclear industry, where there is a need to maintain precise and assured
operation," Scobie wrote. "They can also be used in the medical
operating theaters with remote surgery. In both areas, functionally safe
operation is critical."
A
key point in the Cortex-R52 is that there is what officials called
hardware-enforced separation of various software tasks to make sure the code
that is critical for safety is isolated. The hardware is managed by a software
hypervisor. Not only does this ensure the protection of the code, but also
lessens the amount of code that must be safety-certified, which makes software
integration, maintenance and validation easier and development faster, they
said.
"The
Cortex-R52's ability to compartmentalize software provides our users with the
best solution for safety without loss of determinism," Fabio Marchiò, vice
president of STMicroelectronics' Automotive and Discrete Group and general
manager of its Automotive Digital Division, said in a statement. "Its
virtualization support simplifies the consolidation of applications and
functions into a single processor, delivering a shorter integration time."
ARM is beefing up its safety technology for the ARM Cortex-R52, a processor designed for self-driving vehicles.
The
Cambridge, England-based company was recently acquired by Japan’s SoftBank for
$31 billion. And now it is expanding its chip designs to include a processor
with the robust, real-time performance needed for autonomous cars.
The
new chip will simplify the path for certification of automotive applications,
industrial robots, and medical operations. The processor — which ARM will
license to other chip manufacturers — must comply with tough safety standards
such as ISO 26262 ASIL D and IEC 61508 SIL 3.
It
will enable applications as diverse as surgical automation, safety management
and automotive powertrain control. STMicroelectronics is the first ARM chip
manufacturing partner to announce it has licensed the high-performance
processor to enable it to create highly integrated system-on-chips (SoCs) for
the automotive market.
“If
these systems go wrong in any way, they can affect life,” said Richard York,
worldwide marketing and business development manager at ARM, in an interview
with VentureBeat. “The R-52 will make it much easier to do increasingly complex
software.”
The
Cortex-R52 offers hardware-enforced separation of software tasks to ensure
safety-critical code is fully isolated. So when one part of the system goes
down, it’s easier to decipher what happened. 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, so
speeding up development as software integration, maintenance and validation is
easier. 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 at
STMicroelectronics, in a statement. “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.”
Denso,
a leading global supplier of advanced automotive technology, is supporting the
launch.The availability of ARM Fast Models and Cycle Models enables software
partners to develop solutions for the processor. They further speed the path to
market as software developers will get access to the Cortex-R52 early in the
design process.
The
Cortex-R52 is 35 percent faster than the previous generation Cortex-R5, which
is already deployed in a range of safety applications. It has achieved a score
of 1.36 Automark/MHz on the EEMBC AutoBench, the highest in its class, using
the Green Hills Compiler 2017.
The
processor has protections against various kinds of random errors, design
errors, and software errors. If it senses a system problem, the processor has
to handle cores such as shutting down a vehicle and bringing it to a safe halt.
So it has to be able to sense, perceive and analyze, make a decision, and acutate
(or execute on that decision).
James
Scobie, product manager for the Cortex-R52, said chips based on the design will
likely be available in 2018.
