smart TV chip
MEDIATEK LOOKS TO USHER IN AI-ENABLED
INTERACTIVE MULTIMEDIA EXPERIENCES.
NEIL TYLER REPORTS
MediaTek has announced a new 4K smart TV chip,
the MT9638, which comes with an integrated highperformance
AI processing unit (APU).
The MT9638 has been designed to support
AI enhancement technologies such as AI super
resolution, AI picture quality and AI voice assistants,
plus variable refresh rate (VRR) and MEMC (motion
estimation and motion compensation) so that graphics
will appear smoother.
The device’s high processing capabilities means
that it has been optimised for visual quality, and will
give global TV makers features to design competitive
4K smart TVs.
“As smart home appliances become more
intelligent and diversi ed, smart TVs are becoming
the new hub for the smart home as consumers take
advantage of AI-enabled multimedia features to control
all their devices right from their TV,” said Alex Chen,
General Manager of the TV Business Unit at MediaTek.
With built-in AI picture quality technology, the chip
enables real-time content and scene recognition,
automatically adjusting colour saturation, brightness,
sharpness, dynamic motion compensation and smart
noise reduction to improve the overall image quality.
MediaTek’s AI super resolution technology,
combined with its MEMC technology, makes it
possible to intelligently upscale resolution through
multi-frame blending to deliver clearer images at the
smart TV’s native resolution.
The chip also supports the latest connectivity
technologies including Wi-Fi 6 and HDMI 2.1, which
integrates support for VRR to match movies or
console gaming frame-rates in order to avoid screen
tearing.
The MT9638 also supports applications powered
by AI voice recognition and AI enabled video calls,
opening up new ways for consumers to interact with
their smart TV.
Compliance Suite targets
secure IoT applications
Secure Thingz, an IAR Systems
Group company, has announced
Compliance Suite, a set of
tools and training for embedded
developers.
These tools and training are
specifi cally targeted to provide
developers with a simplifi ed path
to building applications that are
compliant with the European EN
303645, UK & Australian 13
Best Practices, and the evolving
US Cybersecurity Improvement
Act (NISTIR 8259).
Compliance is a challenge
when it comes to the fast-moving
Internet of Things domain so
the IoT Security Foundation
has developed an IoT Security
Compliance Framework, enabling
organisations
to build a selfcertifi
cation
methodology that
meshes with the
13 Best Practices
captured in UK
and European Secure by Design
guidelines.
The Compliance Suite
includes a set of development
tools and Preconfi gured
Security Contexts that
enables developers to rapidly
implement core aspects of the
guidelines, such as moving
from passwords to certifi catebased
identifi cation; the
implementation of update
policies; and the use of
advanced device specifi c
security enclaves to protect
provisioned information.
Coupled with these tools
is a set of training and
support resources linking the
functional requirements with
the certifi cation requirements
identifi ed in the IoT Security
Foundation Compliance
Questionnaire, ensuring a rapid
implementation that meets
international requirements.
SMART Modular
launches DDR5
Module family
SMART Modular Technologies
has launched its DDR5 module
family of products, as it looks
to support the transition to
higher-performing, more ef cient
memory technologies.
DDR5 has been designed
to provide increased memory
bandwidth and performance to
help process data across various
application segments including
HPC, AI, and edge computing and
provides twice the performance
of DDR4 with a 4.8 Gbps to 6.4
Gbps data rate and improved
power ef ciency over DDR4 by
using an on-DIMM 12V voltage
regulator (PMIC) and 1.1 I/O
voltage.
Another important factor
contributing to its higher
performance is its dual-channel
DIMM topology for higher
channel ef ciency that makes
it suitable for growing server,
cloud computing, and enterprise
networking applications.
DDR5 is able to achieve
increased performance by
doubling the burst length to BL16
and bank-count to 32 from 16 on
DDR4. For increased reliability
and ef ciency, DDR5 DIMMs also
have two 40-bit fully independent
sub-channels on the same
module and have a maximum
die density of 64Gb with the
capability of scaling to much
higher DIMM storage capacity
than DDR4 DIMMs.
SMART Modular’s initial DDR5
module product family includes
RDIMMs, UDIMMs and SODIMMs
in densities ranging from 16GB
to 64GB.
