1 EXECUTIVE SUMMARY
STMicroelectronics (ST) has pioneered system-on-chip (SOC) integration to help customers
reduce cost and power consumption while improving reliability. At the same time, ST has been
at the forefront of the digital multimedia revolution, providing the consumer electronics industry
with highly integrated platform-based solutions.
As a leading supplier of integrated circuits (ICs) for mobile phones, ST also aims to make compelling
multimedia a practical reality for handheld devices. An intensive development effort has
led to an outstanding application processor that enables smart phones, wireless PDAs, Internet
appliances and car entertainment systems to playback media content, record pictures and
video clips, and perform audiovisual communication with other systems.
This new processor platform, called Nomadik, is a culmination of breakthroughs in video-coding
efficiency, inventive algorithms and chip implementation schemes, and strategic collaboration
with leading companies in the mobile industry. The Nomadik platform offers device
manufacturers the following competitive advantages:
● Ultra-low power consumption for longer battery operation,
● Unsurpassed audio and video quality,
● Easier application development for shorter time-to-market,
● Scalability for multiple market segments and future multimedia applications.
In an ideal world, open hardware and software interfaces would encourage mobile product and
content innovation. The perfect mobile terminal architecture would be easy to program, use a
non-proprietary CPU, and be operating system (OS) and radio modem agnostic to give manufacturers
complete freedom to differentiate their products.
The Nomadik platform was developed specifically to enable this vision of an open mobile architecture.
Software development is simplified with high-level language programming on the
industry-leading, licensable CPU (ARM®) architecture. This architecture includes Java acceleration
for efficient run-time execution and is supported by a comprehensive development
tools environment.
A shared framework with open application-programming interfaces (APIs) allows multimedia
plug-ins to run across supported products. ST defined these standard interfaces in partnership
with other industry leaders to reduce development efforts and shorten time-to-market. Physical
layer abstraction decouples application software from the underlying platform architecture.
This permits rapid, technology-driven Nomadik platform evolution without sacrificing performance
or code interoperability.
The Nomadik platform raises the standard for mobile multimedia performance and enables ingenious
products that bring real value to the end user. Furthermore, the open Nomadik platform
is defined by shared standards, protocols, and interfaces to stimulate mobile innovation
and market growth.
