The Symbian Smartphone Show, London, UK, October 11th 2005 - At The Smartphone
Show today Symbian Limited unveiled the Symbian OS™ Real Time Compatibility Layer
(RTCL).
This unique technology further enhances Symbian OS's suitability
as a platform for the development of lower cost, higher volume, mid-tier phones
by reducing build and development costs for phones based on Symbian OS.
The Symbian OS RTCL enables proprietary signalling stacks to run on Symbian OS.
Smartphone and advanced phones are usually based on designs that use two processors,
one processor to run the GSM / EDGE / UMTS signalling stack, and a second processor
to run Symbian OS. By using Symbian OS RTCL to host the signalling stack, handset
makers can seamlessly migrate from two processors to a single processor architecture
while still benefiting from the advanced features and high performance of Symbian
OS. Because Symbian OS can be run on lower cost hardware platforms traditionally
aimed at high volume feature phone and voice-only phone markets, this development
provides handset makers with significantly lower phone build and development costs.
The Symbian OS RTCL provides API-level compatibility with leading RTOSs, enabling
code to be ported with a simple recompilation. Simplifying migration to Symbian
OS still further, existing RTOS toolchain and binary formats can be preserved,
avoiding the need to fix legacy problems and so further reducing the cost to handset
manufacturers of developing mass market phones based on Symbian OS.
As part of the RTCL testing process, Symbian and a leading stack vendor have
successfully made both voice calls and run GPRS data on Symbian OS. The Real
Time Compatibility Layer exploits the advanced real-time capabilities of Symbian
OS's real-time kernel architecture - introduced in Symbian OS v8 - to enable Symbian
OS to host the signalling stack and meet its real-time processing requirements.
Symbian will be making the RTCL available to Symbian OS in future releases of
Symbian OS.

"The Symbian OS Real Time Compatibility Layer makes it easier for handset manufacturers
to take advantage of Symbian's real time kernel and build Symbian OS smartphones
using the same lower cost single processor hardware platforms that are used to
build midrange phones," said Charles Davies, CTO, Symbian Limited. "This will
help drive Symbian OS into higher volume segments."
