ARM
has launched a new processor aimed at real-time automotive, industrial
and medical applications. The ARM Cortex-R52 advanced safety processor
addresses functional safety in compliance with the stringent ISO 26262
ASIL D and IEC 61508 SIL 3 standards. ARM partner STMicroelectronics is
the first company to license the processor for use in an SoC targeting
the automotive market.
ARM
Cortex-R52 Key Benefits
·
- Streamlined
next generation system development with the highest level of integrated
functional safety features
· -
Simplified
integration of complex software through strong separation of mixed criticality
code without impacting real-time performance
· -
Address
higher workloads with increased performance compared to Cortex-R5
James
McNiven, general manager for CPU and media processing groups at ARM, provided
some background information about the new processor's development: "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." To meet the industry safety standards
ARM has documented the strict development process, fault modelling and
supporting software isolation for the Cortex-R52.
A
functionally safe system must be protected against the occurrence of both
random and systematic errors. In an example of the car braking system, the
safety application will protect against both random hazards that can disrupt
your vehicle, and systematic issues such as design and software errors.
The
new processor works by implementing hardware-enforced separation of software
tasks. This ensures that safety-critical code is fully isolated. With this
system built-into the processor less code needs to be safety-certified, aiding
development, integration, maintenance and validation of software. In addition,
the processor design provides fast context switching that real-time systems
demand.
STMicroelectronics
will be using the ARM Cortex-R52 advanced safety processor in smart driving
applications controlling the powertrain, chassis and ADAS (Advanced Driver
Assistance System). DENSO, a leading global supplier of advanced automotive
technology, systems and components is also supporting the launch.
ARM's
new Cortex-R52 offers a 35 per cent performance uplift compared to the
Cortex-R5, which is already deployed in a range of safety applications. The new
processor scores 1.36 Automark/MHz on the EEMBC AutoBench, the highest in its
class, and is 14x faster at context switching.
For
those interested in reading further, ARM has published a comprehensive blog
post about the new Cortex-R52 safety processor.
ARM,
the British chip designer powering the global mobile phone industry, launched a
new processor on Tuesday for driverless cars, seeking to secure its place at
the heart of the burgeoning industry.
Bought
by Japan's SoftBank for $32 billion this month, ARM said the processor was
designed to increase safety in increasingly complex systems and could work
across a range of industries from autonomous vehicles to industrial and medical
robotics.
The
Cortex-R52 processor, which has been under construction for between 3 and 5
years, has been licensed to Franco-Italian chipmaker and partner
STMicroelectronics in its first deal.
ARM
said the processor was designed to keep the most critical software code
separate, in order to protect the running of the platform. That would enable it
to improve safety when a car wants to overtake, accelerate or break suddenly,
for example.
"If
you have a piece of safety critical code, you want to be sure that nothing can
interfere with that," John Ronco, VP Product Marketing, told Reuters.
The
26-year-old ARM, based in Cambridge, eastern England, provides the technology
in nearly all smartphones including Apple's iPhone and Samsung's Galaxy.
It
is also poised to play a central role in the tech industry shift to the
'internet of things' - a network of devices, vehicles and building sensors that
collect and exchange data.
"What
we see is that all of these systems have a similar technology platform, a
similar framework in terms of what they're doing, and they have the same
requirements in terms of having processors that can safely make decisions about
what the system should do," Ronco said.
Autonomous
or driverless cars are seen as the next big thing for the tech industry, with
the British government putting the market value at 900 billion pounds ($1.17
trillion) worldwide.
Traditional
automakers face competition from rivals such as Tesla and technology firms such
as Alphabet Inc's unit Google, which wants eventually to be able to deploy
fully autonomous vehicles without human controls.
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.
