Key features of OMAP2430 processor:

• Advanced Imaging, Video and Audio Accelerator (IVA 2) boosts video performance in mobile phones by up to 4X and imaging performance by up to 1.5X
• Delivering a multimedia experience with consumer electronics quality to the handset
• Multi-engine parallel processing architecture for supporting complex usage scenarios
• Built-in M-Shield mobile security technology enables value-added services and terminal security
• Support for all major High Level Operating Systems (HLOS) aids applications development

OMAP2430 supports embedded operating systems, including Linux, Symbian and Windows Mobile. Embedded OS enable manufacturers and mobile operators to differentiate their products through:

• Friendly and powerful user interfaces, with support for a rich array of applications and services, and the ability to customize according to operators’ needs.
• Robust, flexible applications and services architecture.
• An extensive network of third-party developers.

OMAP2430 processor has a built-in M-Shield Security Technology, enabling operators to add value-added services for transaction security, content protection, secure network access and also terminal security functions.

M-Shield Mobile Security Technology
TI’s M-Shield Mobile Security Technology is a system-level security solution that intimately interleaves hardware and software technologies to provide the high level of security. M-Shield technology is the key security element of the widely used OMAP platform and OMAP-Vox. M-Shield provides the highest level of terminal and content security in the industry today, as well as setting the benchmark for the level of security needed to allow financial applications to happen.

The OMAP2430 and TWL4030 combination boost system performance, maximize battery life and reduce board space.

TWL4030
The TWL4030 is audio and power manager to a host of OMAP processors. It is an integrated power management and audio codec device intended for use in cellular telephone designs which derive their power from batteries based on Lithium-Ion, Lithium-Ion Polymer or Cobalt-Nickel-Manganese chemistries. TWL4030 combines power management, DC/DC converters, audio and voice codec, amplifiers (audio), USB 2.0 transceiver, battery charger circuitry into a single chip. The TWL4030 includes stereo/mono audio support for speakers, headsets and earpiece, analog/digital microphone, analog and digital mixing and  noise cancellation circuitry. The battery charger system supports for charging via USB, carkit, and AC adapter. TWL4030 also features battery presence and over voltage detection, and battery back-up management.
