OMAP4470 移动应用处理器

OMAP4470 移动应用处理器
OMAP4470 mobile
applications processor
Building upon the strengths of the OMAP4460
processor, the OMAP4470 is the first OMAP™
processor designed for mobile computing, with
enhanced graphic and memory performance
to support intense computing applications and
operating systems.
As part of Texas Instruments’ (TI) OMAP 4
processor family, the OMAP4470 extends TI’s
expertise in powering high-end smartphones to
the rapidly growing tablet and ultrathin laptop
market. Like the other OMAP 4 processors,
the OMAP4470 centers around two ARM®
Cortex™-A9 MPCores that support symmetric
multiprocessing (SMP) and deliver speeds up
to 1.8 GHz each. These complemented by
two ARM Cortex-M3 cores that can offload
real-time processing functions, lowering overall
power consumption. Other key architectural
features include an Image Signal Processor
(ISP) and IVA 3 accelerator offering unparalleled
imaging and video performance and supporting
multiple video encode/decode standards, and a
programmable DSP.
The OMAP4470 processor architecture has
been enhanced to deliver top-notch graphics
by increasing its predecessor processor
specifications in a balanced manner. In addition
to the latest-generation 3D graphics core –
Imagination Technologies’ POWERVR SGX544,
the OMAP4470 system-on-chip (SoC) includes
a dedicated 2D composition engine. This
composition engine is able to accelerate rich UI
composition with multilayer blending with transparency on high resolution displays to allow

Latest-generation graphics for the
operating system and beyond
The OMAP4470 processor includes the
latest-generation graphics core from
Imagination Technologies, the POWERVR
SGX544. SGX544 offers more than two times
the performance of the previous SGX540 core.
This core provides full support for DirectX with
maximum hardware acceleration, making it
ideal for tablets, computing devices and
smartphones. In common with all POWERVR
Series5XT cores SGX544 delivers all the
benefits of SGX cores, including the highest
processing power per mm2 and per mW ,
unified shader architecture, tile-based
deferred rendering, and low power.
SGX544 provides comprehensive market
proven support for desktop OpenGL 2.1
(including X11 integration with DRI2, EXA
and DRM support), OpenGL ES 1.1 & 2.0,
OpenVG 1.1 and OpenCL 1.1 Embedded
Profile, offering the widest ranges of supported
APIs of any mobile or embedded graphics
IP core available today. POWERVR SGX software
stacks have passed rigorous Khronos and
Microsoft conformance tests, guaranteeing
fast time to market with high confidence across
the widest range of embedded and desktop
operating systems.
Rich user interfaces, deep resolution
Rich, distinctive user interfaces are quickly
becoming a differentiator for mobile devices.
There are two primary factors necessary for
this progress: high screen resolution and an
increasing number of layers used to compose
and overlay the UI. The OMAP4470 processor
architecture enables OEMs and ODMs to
support up to QXGA (2048x1536) resolution
with UIs composed of more blended layers
than the original OMAP4430 device and up
to two times more layered imaging and video
composition than competitive solutions.
Dual-channel memory
When this interface richness is combined
with the super responsiveness enabled by
OMAP4470’s dual-channel memory,
consumers get extreme multi-tasking ability
and download times. The dual-channel
architecture enables 100 percent higher
bandwidth than the conventional single-channel
architecture allows. It maintains a higher
number of instructions actually executed by
processor cores as usage gets more complex
and consumers run more intensive applications
or multiple screens compared to single-channel
architecture, even when running at the same
speed.
This means OMAP4470 devices can
maintain very high user experience running
a combination of applications when
performances would collapse on a
conventional single channel memory.
Dual-channel memory, together with the
OMAP4470’s enhanced 2D and 3D cores
allows it to offer up to two times the numbers
of blended UI layers required for tomorrow’s
rich UI compositions.
MCU performance (eMIPS)
The SMP Advantage
In line with the OMAP family’s heritage of
delivering high performance and low power,
the OMAP4470 processor supports SMP
parallel processing for higher performance
and efficiency. SMP allows identical processing subsystems to run the same instruction
set; have equal access to memory, I/Os and
external interrupts; and run a single copy of
the operating system to control all the cores.
SMP’s scalable performance activates only the
cores that are needed for a particular process
to reduce power consumption or substantially
increase performance.

IVA 3 Hardware accelerator
The third-generation IVA on the OMAP 4
applications processor is divided into two
sections: a power-optimized, multi-format
hardware accelerator for mainstream codecs
and a programmable digital signal processor
(DSP) based portion for emerging codecs and
audio. IVA 3 delivers up to 1080p30 encode/
decode and up to 1080p60 Internet content
playback on the broadest set for multimedia
codecs available today, including, but not
limited to:
• H.264 HP
• MPEG4 ASP
• VC-1 AP
• MPEG2 MP
• ON2 VP7 and VP8
Display sub-system
The OMAP4470 display sub-system is a flexible
multi-pipeline system that supports multiple
high resolution displays, including multi-touch,
to deliver larger, color-rich viewing of local or
external displays. The platform can interface
to MIPI-compliant serial displays as well as
parallel displays. To drive external displays, the
OMAP4470 includes an integrated HDMI v1.4a
3D transmitter with High-bandwidth Digital
Content Protection (HDCP) and deep color
support can drive an external HD display from
the handset, making it easy to share multimedia
content.
Imaging sub-system
The OMAP4470 imaging sub-system includes
a flexible yet powerful image signal processor
that is capable of supporting camera sensors
up to 20-megapixel resolution at less than
one-second shot-to-shot delay, comparable to
the best digital still cameras available. The ISP
also supports advanced image processing and
quality enhancement features such as, but not
limited to:
• Digital anti-aliasing
• On-the-fly defect pixel correction
• Lens-distortion correction
• Edge enhancement
• Noise filtering
• Stabilization
• Auto-focus/auto-white balance/
auto-exposure
• Digital zoom
• Face detection
The OMAP 4 applications processor’s ISP is
able to capture high quality digital pictures and
provide greater design flexibility while saving
printed circuit board (PCB) area, design cost
and system power.
OMAP 4 platform security
TI’s M-Shield™ mobile security technology is
a hardware and software solution that enables
robust protection of premium copyrighted digital
media content, secure protocol applications
and e-commerce applications such as ticketing,
banking, brokering and shopping. M-Shield
is based on open APIs and provides an
environment for secure applications that
deliver robust performance, interoperability,
greater development speed and large
economies of scale. Devices with M-Shield
technology are enterprise-ready thanks to
best-in-class device integrity and data
protection service.
Software and support
TI provides a comprehensive software suite
that supports the leading mobile OSes,
including Microsoft Windows and Linux
(Android, Chrome), and is integrated and
tested up to the application level, enabling
faster and easier development for end
equipment manufacturers and application
developers. Additionally, the software platform
has been performance and power optimized
for the OMAP 4 platforms to ensure the
highest performance in customers’ products.
The software suite allows OEMs and partners
to spend their resources on differentiating
their product at the user interface and
application level while reusing most of the
system platform software components
directly from TI.
All OMAP platforms are backed by TI’s
extensive development support. Code
compatibility among processors makes it
easy to port software and a sophisticated
development environment speeds
programming for all on-chip processors.
In addition, the OMAP ecosystem provides
access to TI Developer Network members
and OMAP Technology Centers (OTCs), as
well as systems integrators, development
tool providers and leading content providers
worldwide.
With an advanced set of features, including
dedicated 2D and 3D graphics, display and
imaging subsystems, high security and a
programmable DSP, the OMAP4470 is the
perfect processor to implement feature-rich,
high-performance mobile computing devices
that offer compelling displays, rich UIs, and
applications for both the consumer and
enterprise markets.
