AmigaOS is the native operating system for the Commodore Amiga, which from the components of Workbench, which Amiga DOS with the command line level CLI (later renamed in Shell) and the operating system core Kickstart present with most Amiga models in the ROM exists.

development

the system by the company Amiga one developed and after their assumption by Commodore 1985 in thatfirst version finished. The component Amiga DOS and parts of Kickstart are based on tri pos, a multi-user operating system of the company MetaComCo, who was developed in the programming language BCPL.

For its time, i.e. between 1985 and 1992, the AmigaOS had outstanding characteristics:

  • 32-Bit-Architektur
  • preemptive multitasking similarly as with Unix - computers (and be enough before Windows)
  • Mikrokernel - architecture with reloadable LIBRARies and device drivers (DEVICEs)
  • programmable real time interrupts with small latency
  • programmable file system devices
  • application-independent printer drivers
  • window-oriented graphic user surface
  • application-oriented Desktops (so-called. Screen) in more differentAn international localization
  • (i18n) is dynamically possible for diagram and color dissolution starting from the version 2.1

the first 68k - CCUs made available still no MEMORY management unit . Therefore the AmigaOS without storage protection had to get along - however was this in the middle of the 80'salso still no topic in the home computer segment.

The Workbench was not needed compellingly for functioning the computer, since the operating system core and many system libraries were contained in the Kickstart ROM, why most computer games were loaded directly with Kickstart around more main storage to useto be able. Thus those were however mostly set multitasking - for characteristics of the operating system except function. Up to the version 3.1 (1994) the AmigaOS was developed by Commodore. For the development of the versions 3,5 (1999) and 3,9 (2000) waren Amiga Inc. and Haage & partners responsible.

Momentarily Hyperion works on behalf of Amiga Inc. at the version 4 of AmigaOS, which first AmigaOS, which no MC 68000 - processors more supported, but exclusive on Motorola PowerPC - row runs.AmigaOS 4,0 stands at present as “Developer Pre release” for order, however exclusively for the AmigaOne platform of Eyetech (by Dongle).

With the help of the GNU AmigaOS can aid programmes be transformed into a unixoides operating system. In this context the editor vim developed,in addition the AmigaOS end of the 80's and at the beginning of the 90's was a time long the main development platform for numerous GNU tools, among other things the GCC.

AmigaOS in relation to other systems

systems MorphOS an alternative

  • derived

from AmigaOSfor the execution of 68k AmigaOS-3.1-Programmen on current PowerPC - hardware in form of the Pegasos - computer family is MorphOS.

For the execution of native PowerPC - AmigaOS4 and MorphOS unfortunately different beginnings, which are not compatible with one another, use software. By supply mutuallyEmulation beginnings (OS4Emu and/or. ppclibemu) from third side on solutions one works here, which lead a prototypeful niche existence for lack of readiness for official co-operation however rather.

  • AROS and depr.

the AROS project is a beginning, a free AmigaOS-3.1-Umgebung on x86-Prozessoren (andto copy other CCUs). In the form of depr. (AROS for AmigaOS) exists likewise a project, which is anxious to make the innovations introduced by AROS available by Rückportierung also under AmigaOS.

  • smartOS

smartOS the project is likewise a free development,which tries to combine the principles of AmigaOS with the possibilities of a CIL of remark system. Beside x86-Prozessoren are to be supported as far as possible also M68k/Coldfire, MIPS, ARM and PowerPC.
