first time, the SGX544 dual-core 3D graphics
acceleration unit and video acceleration for a
1080p HD stream have been integrated in a TI
Sitara processor, enabling the MCU to drive
multiple displays.
For industrial automation applications, the
AM572x processor provides significant ben-
efits resulting from its two on-chip instances
of the PRU-ICSS (Programmable Real-time
Unit – Industrial Communication Subsys-
tem), providing support for almost all indus-
trial fieldbus protocols. Cooperating with
third-party suppliers, TI provides stacks and
firmware for Profibus, EtherCAT, Profinet,
and EtherNET IP slave operation. In addition,
master configurations are planned for Profi-
bus and EtherCAT. Stacks and firmware have
been integrated and tested in the TI System
Development Kit (SDK) for TI-RTOS (Real-
Time Operating System), which can be down-
loaded for free at the company website. The
TI-RTOS kernel is a basic real-time operating
system specifically designed for TI products.
The on-chip C66xx DSPs provide an addi-
tional advantage for industrial automation
applications. For instance, they can be used
to implement motor monitoring and error
detection schemes. For this purpose, the DSPs
are accessed via OpenCL in order to perform
a spectrum analysis based on the FFT algo-
rithm (Fast Fourier Transform). By detecting
motor frequency variations, this reveals any
imbalances or other faults.
Phytec develops the phyCORE-AM57x pro-
cessor module based on the AM572x proces-
sor. With the feature set described above, the
module lends itself particularly to HMI, avia-
tion control, industrial automation, machine
vision, medical imaging, and networking appli-
cations. Using the phyCAM-P interface, cam-
eras and automotive sensors can be connected
to the phyCORE-AM57x processor module. To
suit different market requirements, the com-
pany uses mechanically robust connectors on
the module. Alternatively, the module can be
directly soldered to the carrier board using the
company’s proprietary DSC technology. The
components were selected based on their long-
term availability, their suitability for industrial
applications and their extended temperature
range. If required, a protective coating is also
available for the module.
A development kit for the phyCORE-AM57x
processor will be provided, facilitating a quick
entry into the design of a custom carrier board
and corresponding applications. The kit con-
sists of the phyCORE-AM57x processor mod-
ule suitable for industrial use and volume
production, a universal carrier board, circuit
diagrams and a comprehensive software pack-
age. The latter includes a build environment
based on the YOCTO project. All relevant
documentation is also included. In addi-
tion, free support is provided for the start-up
phase. The complete microelectronics stage is
manufactured by Phytec at its Mainz factory.
The company provides customers with insight
into the production process in order to nego-
tiate any customizations that might be neces-
sary in the manufacture of certified products.
The example described demonstrates how
module providers can cooperate with semi-
conductor manufacturers in order to design
modules matching the high performance and
complexity level provided by modern proces-
sors. The integration of EMC-critical compo-
nents into the module also reduces the time to
market and the design effort required for cus-
tomer projects. Consequently, module design
can start while the processor is still prepared for
volume production. In addition, the modules
provide guaranteed long-term availability and
are suitable for industrial applications. By let-
ting all project partners concentrate on the core
competencies, this concept brings sustainable
advantages for industrial customers who also
benefit from the elimination of lengthy and
costly in-house development projects.
