TI AM5K2E04 Applications of the k2h and k2e platforms in high-end imaging Datasheet

Industrial Imaging
Applications Brief
Applications of the K2H and K2E platforms in
high-end imaging
TI’s K2E and K2H System-on-Chip (SoC)
platforms, based on the KeyStone II
multicore architecture, are 28-nm highperformance platforms that deliver powerefficient processing solutions for high-end
imaging applications. These devices are
the first to integrate ARM® Cortex™-A15
MPCore™ processors with high-performance
TMS320C66x DSP cores, providing
heterogeneous processing at industry-low
power-consumption levels.
The integration of the Cortex-A15 pro­
cessors greatly reduces system cost and
design complexity by removing the need for
a high-end general-purpose processor. With
full support of SMP Linux™, the Cortex-A15
processors enable developers to quickly and
easily migrate existing software designs to the
low-power, high-performance K2E and K2H
platforms.

Ethernet
ARM-based Linux device integrated with the
industry’s highest-performing DSP cores in a
single power-efficient package that can deliver
up to 352 GMACS, 198 GFLOPS and 19,600
Dhrystone MIPS. Coupled with industry-best
development tools and multicore software
support for OpenMP® and OpenCL™,
developers can easily parallelize code and run
it on the ARM or DSP cores and quickly create
code that scales across the different devices
within the K2H and K2E platforms, allowing for
the most cost- and power-efficient designs.
Application Segments
Industrial Automation: Industrial automation
systems are implemented to increase
production throughput and productivity and
to improve the quality and consistency of a
product or process. These systems perform a
wide array of functions including:
• Image location and enhancement
• 1D/2D code reading
• 2D/3D pattern matching
• Background modeling and subtraction
• Object feature extraction
• Edge detection
• Dilation and erosion
• Thresholding
• Image warping
• Optical character recognition (OCR)
• Edge- and surface-based inspection
• Defect identification and classification
• Feature and tolerance verification
• Color identification
The combination of these functions in
an industrial automation system requires
significant real-time processing. These
processing functions can be implemented in
a smart industrial imaging camera with a lowpower, high-performance processor like TI’s
TMS320C665x multicore DSPs which provide
enough processing power to do many industrial
automation functions while remaining within
the power limitations of the camera.
Where more processing is needed or post
processing analysis is desired, a multi-headed
processing unit taking input from several
cameras in a centralized vision processing
unit as part of a comprehensive industrial
automation system is deployed, as shown
in Figure 2. This central system typically is
responsible for most of the analytic processing.
The K2E and K2H SoC platforms provide
an elegant, scalable solution for this type of
centralized processing in industrial automation
systems.
With the Cortex-A15 processors in the K2H
and K2E devices and the development tools
and programming models available from TI,
developers have the ability to support full ARMbased Linux™ systems while offloading the
real-time processing to the high-performance
C66x cores. The offloading of real-time
processing enables a more power-efficient,
high-performance centralized processing unit.
For more complex systems requiring additional
processing capacity, TI’s HyperLink can be used
to connect multiple KeyStone devices adding
additional C66x DSP cores and/or Cortex-A15
processors.
Because the processing elements of
the KeyStone SoCs are programmable and
scalable, the system has maximum flexibility,
allowing the same processing system to
be used across different product lines. The
scalability is further expanded because the
C66x cores in the K2H platform are the same
as those in the C665x platform. Therefore,
code developed for the C66x core that is used
in the central processing unit can migrate to
the smart automation camera and vice versa,
allowing maximum reuse and scalability.
Video Surveillance: Video surveillance appli­
cations will also benefit from TI’s K2H and K2E
platform of devices. This is particularly true in
the popular network video recorder (NVR) and
digital video recorder (DVR) hybrid, known as an
NVR/DVR, and the standalone analytics servers.
These end equipments get their video
content through a network connection and
may have to encode/transcode the video
before storing it. Video can then be retrieved,
decoded/transcoded when necessary, and
have various analytics algorithms run on all or
parts of the video stream. Common analytic
algorithms used in surveillance are:
• Tamper detection
• Motion detection
• Trip zone/boundary crossing
• Object detection/removal
• Object identification
• Object counting
• Object tracking
• Behavior analysis
• Facial recognition
• License plate recognition
TI’s KeyStone II SoCs are well equipped
to handle the combination of the NVR/DVR
functionality and the need for processing the
analytics algorithms listed above.
KeyStone II devices feature a network
coprocessor AccelerationPac. This
AccelerationPac consists of a packet
accelerator and a security accelerator that
work in tandem to offload the DSP and
ARM cores. This enables high-performance
network application processing while freeing
the C66x DSP and Cortex-A15 processors for
other functions like analytics, video encode/
decode, running the operating system (OS)

Figure 2 – Example of 66AK2H06 SoC used as the main processor in a multi-head vision controller used to control multiple cameras and run analytics in an industrial
automation system
and executing control code. The security
accelerator provides security processing for a
number of popular encryption and decryption
modes and algorithms, including IPSec, SCTP,
SRTP, 3GPP and SSL/TLS.
The C66x DSP cores in the K2H platform
are ideal for running advanced analytics
algorithms. Providing both fixed- and
floating-point capability and high-speed
device interconnectivity through HyperLink
to connect multiple KeyStone devices, the
K2H platform provides a scalable solution
to fit the processing needs of any NVR/DVR
system, including software implementations of
advanced codecs like HEVC.
With the Cortex-A15 processors integrated
into the same K2H platform, or available
stand alone in the K2E platform, developers
have a full ARM-based Linux system allowing
quick and easy migration to the low-power,
high-performance KeyStone II devices while
eliminating the need for an additional generalpurpose CPU.
Other Applications for High-End
Imaging Include:
• High-end inspection systems
• PLC in industrial automation
• Industrial printers/scanners
• Currency/counterfeit detection
Development Support
Texas Instruments’ investment in hetero­
geneous software tools makes programming
and development simpler than ever. TI provides
a free, downloadable Multicore Software
Development Kit (MCSDK) which includes
highly-optimized libraries and platform-specific
drivers. TI also provides optimized single
and multicore libraries for FFTs, image and
video analytics, matrix math, and many other
commonly used functions and algorithms.
The multicore software development
tools include support for OpenMP®, making
it easier than ever to repurpose complex
application software, and OpenCL™ which
simplifies offloading tasks to the C66x DSP
cores. Algorithm and system developers
can recompile OpenMP code with TI’s Code
Composer Studio™ Integrated Development
Environment to run in supported KeyStone
devices with little modification, substantially
reducing the traditional porting time to
embedded architectures.
TI has numerous demonstration systems
available to help developers see a complete
system and to get up and running quickly.
These include an industrial imaging
demonstration and an image-processing
demonstration that is incorporated into TI’s
MCSDK.
TI also provides free video codecs for
the C66x DSP which come with production
licensing and are available for download.
Additional codecs are available via TI’s Design
Network.
