Symbian – An Intro

Overview
Symbian is an open source operating system and software platform, which is designed for Smartphones and is retained by Nokia. It was originally developed by Symbian Ltd, which was a software development and licensing company that was established on June 24, 1998 as a partnership between Psion, Ericsson, Motorola, and Nokia. However, Nokia completely acquired the Symbian Ltd. in April 2009 and a new non-profit organization, Symbian Foundation, was established. However, Nokia’s Symbian professional services department, which was not transferred to the Symbian Foundation, was sold to the Accenture consulting company on July 18, 2009.

The objective for developing the OS was to distribute the source code for the complete Symbian platform in the OSI (Open Source Initiative) and FSF (Free Software Foundation)-approved EPL (Eclipse Public License). The source code was published on February 4, 2010, which was reported as the largest codebase transitioned in the history of open source by the Software Foundation. However, in November 2010, the Software Foundation stated that because of a lack of support from funding members, it would transition to a licensing-only organization.

Road to Symbian OS

EPOC – It is a family of graphical operating system, which was developed by Psion for portable devices.

EPOC16 – It was a 16-bit pre-emptive (act of temporarily interrupting a task) multitasking OS, designed to be delivered in ROM and was written in Intel 8086 assembly language and C. MC200 and MC400 were the first EPOC16 devices, which was shipped in 1989.

EPOC32 – A pre-emptive multitasking operating system, which was originally developed for the ARM-family processors that include ARM7, ARM9, Strong ARM and Intel’s XScale processor. The first release was appeared on the Psion Series 5 ROM v1.0 in the year 1997. Later on, there were five releases that appeared on ROM v1.1, Revo/Revo Plus, Psion Series 7 and Psion Series 5mx. It was written in C++.

Symbian OS 6.0 and 6.1

Two DFRDs (Device Family Reference Design), Quartz and Crystal, were blended with Ericsson’s Ronneby design that became the source for the UIQ (User Interface Quartz) design. It reached the market as the Nokia 80 Series UI. Later, DFRDs were Ruby, Sapphire and Emerald that evolves into the Pearl DFD and finally to the Nokia Series 60 UI. Nokia 7650 Smartphone was the first phone, which was featuring Symbian OS 6.1 and built-in camera with VGA having a 640 x 480 resolution.
