OMAP processor
for e-readers
™
TI’s second generation of e-readers includes a new software electrophoretic display (EPD) controller-based solution
that allows customers to differentiate, innovate and create the ultimate user experience.
Product Bulletin
Overview
TI’s latest OMAP36xx application processor
is the first well-proven, high-performance,
800-MHz Cortex-A8-based solution for
e-readers using a software EPD controller.
It will allow designers to deliver an
outstanding user experience so that
consumers can use e-books in new ways.
Differentiate and innovate
TI’s powerful E Ink-certified DSP software
EPD controller is implemented in such a way
that it can support multiple types of displays.
Compared to non-upgradable fixed hardware
solutions (which do not allow for differentiation),
the ability to bring constant updates and
customizations to the software controller is a
powerful weapon that allows our customers to
stay on top of technology and market needs.
Improved system cost
TI’s OMAP3621 has been designed to
address the trade-off between cost and
performance. Our goal is to satisfy our
customers’ need for sleek and modern
designs while improving power consumption
and user experience. Using low-power DDR,
a smaller package allows our customers
to create a very lightweight, thin modern and
low-power-consumption device that will satisfy
even the most demanding consumers.

Manufacturing capabilities
TI’s reputation makes it a trustworthy supplier
that can deliver high-quality products in large
quantities.
Extended battery life
Battery life is the No. 1 top priority for end
customers. TI’s well-proven, best-in-class
power management techniques have satisfied
the Smartphone market for many years. Our
well proven experience, when brought to the
consumer market, improves the overall user
experience.
E-readers support structure
TI’s consumer business line offers a strong
baseline of support, reinforced by trained FAEs
around the world. We believe that high-quality
products are developed with high-quality
support.
High-quality analog
TI’s e-book development platform incorporates
high-quality analog devices. Many analog
devices have been optimized to best interact
with each other, further optimizing platform
performance and overall product quality.
TI’s wide analog portfolio allows customers
to customize their platforms.
E Ink-certified software EPD controller
TI’s OMAP™ 3 e-book solution employs a
unique DSP-based software controller to drive
E Ink’s Vizplex electrophoretic displays whether
they are black and white or color.
OMAP3611 PDF performance
(Cortex-A8 running at 600 MHz only)
Benchmark conducted on three PDF files
stored on an SD card and rendered, scaled
and displayed on 16 levels of grayscale
(4-bit) monochrome display. Decoding done
on Cortex-A8, with no specific hardware
acceleration or optimizations.
New EPD controller software version 2
• EPD controller software version 2
- Unlimited partial update: software can
re-write in a “zone” being updated
- Per-pixel driving : mouse pointer, fast
menu, easy handwriting
- Keeps software compatibility with
version 1 controller
- Flexibility to be updated (OTA)/improved
• What it will mean for OEMs
- Ease of programming to best take
advantage of the software EPD controller
- Simple API
- Non-EPD-aware applications will perform
well with the software EPD controller
using generic API
- EPD-aware applications can use
dedicated API for best-in-class effects
• What it will mean for end users
- Smoother and improved user interface
- More applications can be addressed
- Handwriting recognition
- Virtual keypad with visual feedback
- Animations
- Games
• Why it’s better than the current hardware controller
- Flexibility to adapt any type of panel and
features (EIH V110, V220, V250, next
gen, LG GIP)
- Software flexibility for color processing
- No limitations to concurrent regional
updates

Advanced power management
at SoC levels
TI OMAP technology is divided into eight
distinct physical power domains, which can
be separately enabled or disabled by software.
TI’s SmartReflex™ intelligent technology
includes improved software techniques that
can be divided into two main categories:
• Active power management.
Power consumed by the switching activities
in the circuits involves all system
components: hardware modules, device
drivers, OS and applications. It employs
three main techniques: adaptive voltage
scaling (AVS), dynamic power switching
(DPS) and dynamic voltage and frequency
scaling (DVFS).
• Static leakage management.
Leakage because of lower process nodes
is always present, even when no logic
operations are performed. We have
introduced a technique called static leakage
management to reduce this leakage.
SmartReflex technologies
Description
Adaptive voltage scaling (AVS)
Maintains high performance while minimizing voltage
based on silicon process and temperature.
Dynamic power switching (DPS)
Dynamically switches modules from active state to
retention or off-state mode when computational tasks are
completed and not needed at the moment.
Dynamic voltage and frequency scaling (DVFS)
Dynamically adjusts voltage and frequency to adapt to the
performance required.
Static leakage management (SLM)
Reduces leakage power by switching the entire device into
a low-power mode when no system activity is required.
Relies on several power modes, from standby to power
off mode.
• Cost reduction by design and R&D
savings:
-Multiple product development (concept/
architecture-phase savings)
-Assurance of high-quality devices and
high-quantity deliveries
-Software investments can be reused
between products
-Retain the benefits of previous
development experiences and
optimizations
-Ready vehicle for fast time-to-market
product development
At the system level:
TI has been the first to introduce a more
optimized and high-performing architecture
to enable wide adoption of e-readers while
improving the overall user experience.
Compared to the first-generation architecture,
TI’s new architecture enables:
• More flexibility
• Lower e-BOM cost
• Higher performance
• Slim and lightweight designs

Lower system cost approach
At the platform level:
In this fast-changing and evolving market,
flexibility and reusability have been critical
to the success or failure of many OEMs/
ODMs. TI’s e-book development system
approach is software-optimized and ready
to address the development of multiple
products based on the same core design
(i.e., multimedia e-readers/tablets), allowing
you to achieve important cost savings.
