What does it mean for automotive processors?
Automotive processors have become a fundamental
enabler for smarter, safer and connected vehicles.
In fact, there’s a direct connection between an
original equipment manufacturer’s (OEM) ability to
support the features their customers care most
about in new automobiles and the capability of
automotive processors, as illustrated in Figure 4 on
the following page.
These automotive processor capabilities include:
• The integration of automotive features and
software platforms to optimize the electronic bill
of materials (EBOM).
• The delivery of a heterogeneous architecture
for best concurrencies, safety, security, power
and performance to address new automotive
use cases.
• Differentiation via image-, signal- and vision-
processing capabilities.
The automotive industry has taken major steps to
achieve the exciting goal of integrating connected
in-vehicle infotainment (IVI) systems, reconfigurable
digital clusters and a number of technologies
categorized under informational advanced driver
assistance systems (InfoADAS) into
a single electronic control unit (ECU)
that creates a safer and unique driving
experience. Texas Instruments (TI)
has invested more than a decade in
“Jacinto” automotive processors, as
well as the many analog companion
chips supporting this trend (see Figure
5 on the following page).

TI’s journey to help the industry revolutionize the automotive cockpit
Designed for automotive safety and robustness, TI’s
“Jacinto 6” automotive processors are a first step to
help redefine the traditional infotainment processor
architecture. “Jacinto 6” devices integrate more
features into the processor without compromising
performance in order to pave the way for an
unparalleled in-vehicle experience.
“Jacinto 6” adds more real-time data-processing
capabilities to the traditional IVI features, enhancing
the driver experience by:
• Strengthening the digital signal processor (DSP)
and vision-processing engines.
• Introducing the InfoADAS software development
kit (SDK), which delivers an automotive-ready
framework for enabling ADAS algorithm
integration into the infotainment SDK.
Taking our concept of informational
ADAS and integrated digital cockpit
to the next stage, TI implemented
real system demonstrations running
on single “Jacinto 6” processors
at the Consumer Electronics Show
(CES) in 2015, 2016 and 2017.
We demonstrated that the unique
“Jacinto 6” heterogeneous architecture
can scale and support multiple cockpit
applications, including those that
require safety such as reconfigurable
digital clusters, to deliver the required
performance like fast boot, high-level
operating system (HLOS), and safety

“Jacinto 6 Plus” devices: built with digital cockpit in mind
Software is one of the biggest investments for
Tier 1 manufacturers/OEMs. Software is also
the pillar of differentiation. With that in mind, TI’s
“Jacinto 6 Plus” device extends the robust and
proven “Jacinto 6” architecture with both higher-
performance cores and additional features. This
combination supports TI’s objectives to both
protect existing software investments and enable
industry trends toward more integration without
compromising performance and time to market.
The “Jacinto 6 Plus” device scalability:
• Facilitates the reuse of existing hardware and
software, with no change other than system
upgrades to route external cameras and
connect additional displays to the processors.
• Allows head-unit features and emerging
analytics/image manipulation, as well as multi-
domain/multi-OS capabilities.
• Gives you the ability to integrate on each of the
infotainment, vehicle and driver domains more
features on a single system-on-chip (SoC), with
robust hypervisor implementation supporting
multiple virtual machines and graphics
processor unit (GPU) sharing.
• Enables shorter time to market by leveraging
the same robust and proven architecture of
“Jacinto 6”, including DSP and embedded
vision engine (EVE) accelerators.
• Supports innovation at a reduced cost by
integrating several new Internet protocols (IPs),
including raw camera Image Signal Processor
(ISP), Camera Serial Interface (CSI)-2 ports and
Controller Area Network-Flexible Data Rate
(CAN-FD), which enable lower system EBOM
and support the next generation of interfaces.
“Jacinto 6 Plus” SoCs come with a dual-package
strategy. Existing “Jacinto 6” customers can easily
upgrade their current hardware and optimize system
BOM while integrating cameras and surround-
view features with minimal hardware impact, or
take full advantage of “Jacinto 6 Plus” capability
and performance for enhanced features such as
augmented reality (AR) heads-up display (HUD)
(Figure 7 on the following page).

“Jacinto 6 Plus” SoC is also the solution of choice
for designers new to the “Jacinto 6” platform
who want reliable, robust and proven technology
to design digital cockpit systems without
compromising time to market, thanks to the mature
hardware and software environment and rich
“Jacinto” ecosystem.
The integrated digital cockpit
Soon, drivers will not only rely on traditional
instrument clusters and the center stack to give
them reliable vehicle and safety information and
access maps and media. They will also expect:
• More complex content, including endless media
selections from any source, 3-D navigation,
ADAS and AR views with the ability to morph
size, shape and colors according to the task at
hand, all seamlessly blended in high definition
on multiple displays.
• Ergonomics to further improve their focus and
attention on the road, including augmentation
with HUD to show relevant driving information in
their direct field of vision.
• Relevant information and safety content
according to current driving situations,
displayed in the center field of vision to pave the
way for autonomous driving.
Any new technology that OEMs intend to use must
meet automotive quality and reliability standards (Ex:
AECQ100, ISO 26262, ASIL-B, etc.) while adhering
to a rigid budget. Similarly, drivers will continue to
push to get more for less: greater perception of road
conditions and the monitoring of every angle of a
vehicle will become standard, as will a richer user
experience by leveraging even further connected
lifestyles in the cockpit.
These demands will reinforce the need for ECU
integration which, at some point, will become
mandatory to meet features at a reasonable
cost. A purpose-built SoC that meets automotive
qualification and safety requirements, enables
software scalability and greater R&D efficiency,
and delivers the necessary performance and
differentiation will become even more fundamental
to support market trends in the automotive industry
(Figure 8 on the following page).

The real challenge won’t simply be to deliver
additional Dhrystone million Instructions per second
(DMIPS) on a general-purpose microprocessor unit
(MPU), Giga floating-point operations per second
(GFLOPS) on a GPU or enhanced multimedia
capabilities, but to have the right balance between
these measures and:
• Support for more complex use cases involving
multi-OS/multi-domain/multi-display capability.
• The necessary isolation of different domains
supporting various Automotive Safety Integrity
Levels (ASILs) and safety requirements.
• The vision analytics capabilities of SoCs, which
will have to scale from entry level to premium on
a single software platform.
Achieving this combination will require not just
a boost in device performance, but redefined
and adapted architectures to support the even-
more demanding integrated digital cockpit use
cases. These requirements tie into TI’s vision and
strategy to drive the future of automotive digital
cockpit SoCs.
