ST-Ericsson Collaborates With ARM to Demonstrate the World’s First Symmetric Multi Processing Mobile Platform Technology on Symbian OS

February 16, 2009

GENEVA, February 16 /PRNewswire/ — ST-Ericsson today announced it will
demonstrate the world’s first Symmetric Multi Processing (SMP)-enabled mobile
platform running on Symbian OS(TM) at a private event, at Mobile World
Congress, Barcelona. The technological breakthrough is the first of its kind
and is based on the ARM(R) Cortex(TM)-A9 multicore processor, which
represents a significant leap from previous generations of
baseband/application processor architectures by providing unprecedented
levels of performance and power efficiency. With the ST-Ericsson mobile
platform, Symbian OS will be capable of running more applications, more
effectively, while also reducing overall power consumption.

The ubiquitous availability of high-speed Internet access is fuelling a
growing demand for PC-like speeds on mobile terminals, which in turn signals
the need for improved computing performance. ST-Ericsson’s new family of
system-on-chip is capable of SMP which allows different processes to be split
among several processors based on performance and power requirements. For
example, a device running multiple applications simultaneously can spread
applications across different processors, while individual computer-intensive
applications can also exploit multiprocessing by means of software
multi-threading, a well-known technique used for PC’s and high-performance

“In anticipation of the growing demand for faster, feature-rich phones,
ST-Ericsson has provided a highly optimized platform that can fully exploit
the benefits offered by multi processing,” said Monica De Virgiliis, Vice
President Wireless Multimedia, ST-Ericsson. The overall system performance is
optimized by balancing the applications across the number of instantiated
CPU’s and their operating frequencies for the best achievable MIPS/mW.

“Having multiple processing cores improves real-time performance and OS
reactivity, creating much more responsive devices and a better user
experience,” she added.

“The result of ST-Ericsson and ARM’s collaboration is increased
performance for media-rich content and applications, such as fast web
browsing, imaging, games and location based services, without compromising
battery life,” said Lee Williams, Executive Director, Symbian Foundation. “We
value the commitment shown by ST-Ericsson and ARM to mobile innovation. This
announcement signals exciting developments for the Symbian platform.”

“This endorsement of the ARM Cortex-A9 MPCore multicore processor by
ST-Ericsson demonstrates the rapid adoption of SMP by our partners, paving
the way for a new category of mobile devices that deliver significantly more
processing performance on demand,” said Ian Drew, EVP Marketing, ARM. “This
milestone has been reached by close co-operation with our partners and it now
offers the potential for device manufacturers to continue the trend of
delivering a more personal mobile internet experience.”


The new platform also integrates ARM NEON(R) accelerators coupled to each
of the two CortexA9 SMP processors, further boosting the achievable
performance and offering unprecedented opportunities to integrate even more
demanding features for the best mobile computing experience possible.
Optimized multimedia firmware will further take advantage of the available
hardware accelerators and multi-processing resources, while maintaining full
compatibility with standard development and integration environments, such as

The system’s highly optimized power management adapts instantaneously to
the wide variety of computational loads induced by mobile computing, while
minimizing power consumption. Symbian OS exploits Dynamic Voltage and
Frequency Scaling (DVFS) in order to determine the optimal processing power
at any given moment, working to ensure consumption of resources without
over-extending the system’s capabilities. The platform’s flexible power
management also exploits Adaptive Voltage Scaling (AVS) which adapts the
voltage to the different characteristics of each single chip, induced by
silicon process variations.

Another big advantage of SMP in mobile applications is more efficient
power consumption, and this benefit will be very visible to the end user.
Multi processing uses lower voltages and will allow users to do much more on
a single battery charge. Instead of a single processor running at full
capacity to complete a task, multiple processors can work half as hard
enabling the entire chip to run at a lower temperature, creating less
leakage. This allows the SMP system to deliver the same level of CPU
performance one might expect from a larger and faster uni-processor CPU,
while using less power.

Next-generation 3G and LTE mobile phones will experience data downloads
of up to 100Mbs, and a new breed of data-intensive Internet applications will
demand never-before-seen levels of processing power from terminals. The
highly optimized ST-Ericsson implementation of the ARM Cortex-A9 multicore
processor delivers scalable and flexible performance on demand, with enough
headroom to handle future applications and services on the horizon.
