Symbian OS to support ARM Symmetric Multi-processor (SMP)

[Barry]

Symbian OS will now support the ARM Symmetric Multi-processor (SMP) architecture. SMP support in future versions of Symbian OS will use multiple CPU cores to provide ‘performance on demand’ – battery life will be improved by accessing cores only when running demanding high-end multimedia applications and powering them down when they are not in use.

SMP CPUs consist of multiple cores which can be individually powered up and down by the operating system. This delivers high performance for high-end applications such as games, browser-based intelligent services, and media-rich applications such as video streaming or TV recording, while offering low power consumption when the device is idle or executing less performance-critical tasks. Symbian believes SMP support is a crucial step in continuing to deliver industry-leading battery life in a world where converged mobile devices offer increasingly performance-demanding features with constant battery capacity.

Symbian has already started to deliver SMP technologies to its customers and will roll out the above incremental developments in future versions of Symbian OS. Details of this will be announced in due course. The first Cortex-A9 MPCore processor-based Symbian smartphones are expected in 2010.
