Background information

Manufactured in high volume, this design comes fully GCF/PTCRB tested, so OEMs and ODMs can save time while delivering mature, reliable technology. The core chipset includes a Nexperia baseband for multi-band operation, a Nexperia application engine for multimedia applications, an RF transceiver, a power amplifier, a power management unit, a battery charger, and a complete protocol stack.

The Nexperia multimedia application engine PNX4008 acts as the central media processing unit, implementing the system switchboard and managing all the incoming and outgoing media streams. Time-critical operations can be spread between the baseband and the application engine, reducing the overhead of multimedia functions. The application engine connects directly to the video peripherals and the cellular baseband, as well as connectivity and broadcasting functions, so its possible to add and remove communication pipes to create a more flexible, customized implementation.

Broadcast capabilities go beyond the standard AM/FM receiver and MP3 capability to include options for TV (DVB-H) reception. Recovered OFDM-coded signals are forwarded to the application engine for stream decoding, post-processing, and display. The design also supports TV Out, for interaction with a home multimedia system.

Connectivity technologies are managed by a subsystem that governs operation of Near Field Communication (NFC), Bluetooth, WLAN, USB 2.0, Ethernet, and interfaces to local mass-storage devices.

The software is designed as a distributed system with multiple processors. This ensures that the investments made in legacy software for the cellular system protocol stack processing can be safeguarded and incorporated in the new system solution. It also enables decoupling of the real-time critical tasks between the communication subsystems and the multimedia processor - so the signal processing tasks of the cellular subsystem dont compete for computing power with those of the audio/video processor. The result is a functional, extensible platform that can be implemented quickly with minimal capital outlay, freeing up resources to create added-value applications software and end-user services.

To make it easier to integrate various middleware and application software components, the application engine uses an embedded version of the Linux Open operating system. This lets system integrators avoid having to integrate a legacy cellular protocol processor stack or its associated proprietary operating system. It also lets integrators take advantage of the many skilled resources and application software components available on the open market.

To support the design, Philips offers the Nexperia Mobile Developers Kit, a simple-to-run PC-based kit developed in collaboration with ARM. It includes industry-leading ARM tools and uses the popular Metrowerks Codewarrior for its development environment. It also comes with a self-guided training pack plus a complete set of documentation (with HTML index). The design also comes with a Linux Integrated Development Environment (IDE) based on the MontaVista DevRocket& IDE and integrates an applications framework based on Trolltech Qtopia development tools.
