Please note that as of October 24, 2014, the Nokia Developer Wiki will no longer be accepting user contributions, including new entries, edits and comments, as we begin transitioning to our new home, in the Windows Phone Development Wiki. We plan to move over the majority of the existing entries over the next few weeks. Thanks for all your past and future contributions.
The ARM (previously, the Advanced RISC Machine, and prior to that Acorn RISC Machine) architecture is a 16/32-bit RISC processor architecture. ARM processors are widely used in mobile devices because of its low power consumption. The ARM architecture provides support for the 32-bit ARM and 16-bit Thumb Instruction Set Architectures along with architecture extensions to provide support for Java acceleration (Jazelle™), security (TrustZone™), Intelligent Energy Manager (IEM), SIMD, and NEONTM technologies.
The ARM processor range provides solutions for:
- Open platforms running complex operating systems for wireless, consumer and imaging applications.
- Embedded real-time systems for mass storage, automotive, industrial and networking applications.
- Secure applications including smart cards and SIMs.
Symbian devices are only ARM based.
