Jacinto 7 Processors Serve ADAS and Auto Gateway Needs

Texas Instruments (TI) has introduced the new Jacinto 7
processor platform. Built on the foundation of TI’s decades of automotive
systems and functional safety expertise, the new Jacinto processor platform
brings enhanced deep learning capabilities and advanced networking to solve
design challenges in advanced driver assistance systems (ADAS) and automotive gateway

The first two automotive devices in the platform, TDA4VM
processors for ADAS and DRA829V processors for gateway systems, include
specialized on-chip accelerators to segment and expedite data-intensive tasks,
like computer vision and deep learning. Additionally, TDA4VM and DRA829V
processors incorporate a functional safety microcontroller, making it possible
for original equipment manufacturers (OEMs) and Tier-1 suppliers to support
both ASIL-D safety-critical tasks and convenience features with one chip. Both
devices share a single software platform, which alleviates system complexity
and cost by enabling developers to reuse their software investment across
multiple vehicle domains.

Through in-bound camera, radar and LIDAR data, ADAS
technology helps cars see and adapt to the world around them. The influx of
information coming into the car underscores the need for processors or
systems-on-chip to quickly and efficiently manage multilevel processing in real
time, all while operating within the system’s power budget. TI’s new processors
execute high-performance ADAS operations using just 5W to 20W of power,
eliminating the need for active cooling.

The TDA4VM processor offers on-chip analytics combined
with sensor pre-processing, enabling more efficient system performance. This
allows OEMs and Tier-1 suppliers to support front camera applications using
high-resolution 8MP cameras to see farther and add enhanced features, such as
drive assist. Additionally, TDA4VM processors are capable of simultaneously
operating four to six 3MP cameras while also fusing other sensing modalities
such as radar, LIDAR and ultrasonic on one chip. This multilevel capability
enables TDA4VM to act as the centralized processor for ADAS and enables the
critical features for automated parking, like surround view and image
processing for displays, enhancing vehicle perception for 360 degrees of

The DRA829V processor seamlessly integrates the computing
functions required for modern vehicles. As vehicle technology advances,
automotive gateways need a flexible processor to manage higher volumes of data
and support evolving requirements for autonomy and enhanced connectivity. The
DRA829V processor is the first in the industry to incorporate a PCIe switch
on-chip in addition to integrating an eight-port gigabit TSN-enabled Ethernet
switch for faster high-performance computing functions and communications
throughout the car.

Combined with the ability to support both ASIL-D
safety-critical and non-safety-critical operations, these computing and
communication features enable OEMs and Tier-1 suppliers to support
mixed-criticality applications on one device. Higher bandwidth on-chip also
allows developers to manage software development and validation in vehicles,
which translates to more dynamic updates and upgrades.

Developers can get started immediately with Jacinto 7
processors development kits, and buy the new TDA4VMXEVM and DRA829VXEVM
evaluation modules on for US$1,900 each. Preproduction TDA4VM and
DRA8329V processors are available now, only from TI, at US$97 in 1,000-unit
quantities. Volume production is expected to be available in the second half of
