control. In a real-time zonal control application, they can consolidate
vehicle dynamics, braking, steering and motor control within zones.
Another key application is real-time safety processing such as in advanced
driver-assistance systems (ADAS) and automated driving.
Carlson sees new, high-capability
processors that enable
expanded use of domain and
zonal architectures as vital to
development of vehicles with
increasing software-defined
sophistication. Along with that,
customer expectations won't
let up, either.
Carlson, who's also had exNXP's
Brian Carlson: Going from
100 'boxes' per vehicle - to four or five.
" The industry is going
through a major
transition on both
the software and
hardware sides -
it's like going through
heart surgery and
brain surgery at the
same time. "
AUTOMOTIVE ENGINEERING
tensive experience in the telecom
sector, said the auto industry
is at something of an inflection
point. " The industry is going
through a major transition on
both the software and hardware
sides, " he asserted.
" It's like going through heart
surgery and brain surgery at the
same time. This is a major undertaking
and it's tens of billions
of dollars per OEM that are investing
to do this, " he opined.
" But they realize that they had
to make this change. If they did
not make this change, they
could become irrelevant. I've
seen this happen in the mobile
[phone] industry. "
Embedded security
The S32Z and S32E, like all other S32 automotive platform
processors, Carlson said, embed a high-performance
hardware security engine (HSE). The firewalled
HSE is the 'root-of-trust' supporting secure boot, security
services and key management with protection
against side-channel attacks. The processors are certified
to ISO/SAE 21434 for cybersecurity.
The S32Z and S32E processors provide fault-tolerance
with fail-operational support for high availability
across multiple applications and are certified for ISO
26262 ASIL D functional safety systems.
S32Z and S32E enablement
As with other processors in the S32 automotive platform,
the new S32Z and S32E processors are enabled
with hardware and software for evaluation, development
and rapid prototyping. They include the company's
GreenBox 3 development platform which integrates
processing, peripherals, networking and connectivity
interfaces in a robust enclosure.
The complete out-of-the-box system with advanced
control applications includes example code, PMICs,
Ethernet switch and transceivers, and CAN transceivers.
A wide range of value-add enablement software and
tools, including the S32Z and S32E Vehicle Integration
Platform (GreenVIP), help accelerate evaluation, development,
proof-of-concept, and time-to-market.
In addition, NXP has a broad and growing partner
ecosystem to help accelerate customer designs, according
to Carlson.
