Texas Instruments’ (TI) OMAP™4 mobile applications platform will redefine the mobile phone of tomorrow with new, innovative user experiences driven by PC-like web browsing, 1080p full HD video record and playback, intuitive user interfaces, location-based services and next-generation social networking applications. The OMAP 4 platform includes applications processors, a comprehensive software suite, power management technology and supporting components to bring nextgeneration Smartphones and Mobile Internet Devices (MIDs) to market quickly. The platform is future proof, offering the programmability and performance headroom to support new and emerging applications and standards. Not only will the OMAP 4 platform accelerate time to market and reduce research and development (R&D) time and costs for handset manufacturers, but its flexibility and openness will enable manufacturers to deliver innovative applications at breakthrough mobile computing performance.
TI tests the OMAP 4 platform for real-world use cases, accelerating time to market and enabling stunning user experiences.
At the heart of the OMAP 4 platform is a powerful system-on-chip that includes the perfect balance of power efficiency and high performance.
The OMAP 4 processor balances processing across four main engines: a programmable multimedia engine based on TI’s C64x DSP andpower-efficient, multi-format hardware accelerators; general-purpose processing based on the dual-core ARM?Cortex™-A9 MPCore™ supporting symmetric multiprocessing (SMP) and capable of speeds of more than 1 GHz per core; a high-performance programmable graphics engine; and an Image Signal Processor (ISP) for unparalleled video and imaging performance.
The OMAP 4 family includes two applications processors, both based on the dual-core Cortex-A9 MPCore general purpose processors: the OMAP4430 operates at up to 1 GHz, while the OMAP4460 operates at up to 1+ GHz. Both processors offer the full variety of subsystems and applications discussed below to deliver hardware and software system solutions that scale across customer roadmaps optimizing time to market, flexibility and R&D efficiency.
OMAP4460主要特性:
The OMAP4460 high-performance multimedia application device is based on enhanced OMAP™ architecture and uses 45-nm technology.
The architecture is designed to provide best-in-class video, image, and graphics processing sufficient to various applications.
The device supports the following functions:

OMAP4460 Pandaboard ES开发系统
PandaBoard ES has an updated OMAP4 PandaBoard with the OMAP4460 processor from Texas Instruments. The development board features two ARM Cortex-A9 (M3) cores that can clock up to 1.2GHz, compared to the dual-core 1GHz cores on the original PandaBoard with the TI OMAP4430. In addition to all the existing features of the OMAP4430 processor-based PandaBoard, the PandaBoard ES also has a DSI expansion header, Bluetooth® low energy-capable WiLink™ 6.0 combo connectivity module and a switch to control bootorder. Like the original PandaBoard, the PandaBoard ES is ideal for the development and enhancement of feature-rich mobile platforms and products and can support Linux-based operating systems. The new PandaBoard ES is software-compatible with the original PandaBoard. Additional information about the board and its technology capabilities can be found at pandaboard.org
