Symbian OS

  1. 2. INTRODUCTION <ul><li>a proprietary operating system, designed for mobile devices, with associated libraries, user interface frameworks and reference implementations of common tools </li></ul><ul><li>produced by Symbian Pvt Ltd. </li></ul><ul><li>currently owned by Nokia ,Sony Ericsson, Panasonic, Siemens AG and Samsung </li></ul><ul><li>a descendant of Psion’s EPOC </li></ul>
  2. 3. More … <ul><li>Market leader with a 70% share </li></ul><ul><li>runs exclusively on ARM processors </li></ul><ul><li>Structure:32 bit micro kernel architecture </li></ul><ul><li>Developing language :Commonly C++ and Java </li></ul><ul><li>Design: event based ,pre-emptive multitasking and multithreading </li></ul><ul><li>Openness :not ‘open’ in the sense of Open source software-the source code is not publicly available </li></ul>
  3. 4. Contd… <ul><li>Applications are object oriented </li></ul><ul><li>Restricted memory </li></ul><ul><li>Optimum memory management performance </li></ul><ul><li>Reduced power consumption </li></ul>
  4. 7. Symbian OS Architecture
  5. 8. Symbian Hardware Architecture
  6. 9. Hardware Platform <ul><li>From the hardware perspective, the core is a system on-chip package that will contain </li></ul><ul><li>ARM® CPU core and various peripherals. </li></ul><ul><li>A printed circuit board (PCB) contains the system components, such as a GSM radio, data storage and so on. </li></ul><ul><li>Integrated memory management unit(MMU), caches, access to the various privileged execution modes, and interrupt and exception handling logic. </li></ul>
  7. 10. Contd.. <ul><li>The CPU, MMU and cache along with a number of peripherals all reside on the system-on-chip. </li></ul><ul><li>These system-on-chips usually include a DMA controller, timers, watch-dog timer, interrupt controller, real-time clock, UARTs, LCD controller, GPIO interface, some internal SRAM, and other bus interfaces. </li></ul>
  8. 11. Application Platforms <ul><li>Series 60: a UI for mobile phones that are </li></ul><ul><li>single-handed operated. In addition to voice communication, multimedia messaging, content browsing and application downloading are the main features of this platform. </li></ul><ul><li>Series 80: a UI for devices with larger horizontal screens. It is used in clamshell devices with a keyboard. </li></ul>
  9. 12. Contd … <ul><li>UIQ : a customizable pen-based user interface platform for media-rich mobile phones based on Symbian OS. </li></ul><ul><li>Symbian OS is also being used in the new Series 90 platform, which is being introduced in the Nokia 7700phone. With a pen input user interface, a horizontal screen and an optional television tuner, the Nokia 7700 brings mobile multimedia to a new level </li></ul>
