A2 is a powerful operating system developed by the Native Systems Research Group,
based on the A2 kernel. The A2 kernel provides a compact runtime environment for the Active Oberon
language (pdf), which supports active objects (threads) directly, and enables the construction of efficient active object-based systems that directly run on
Above the kernel layer, a flexible collection of modules provide generic abstractions for devices and services, e.g., file systems, user interfaces, networking, codecs and more.
A relatively large number of applications is available for the A2 system. For example:
- Media Player (DivX, MP3)
- Programming Editor
- Web Server
- Oberon for A2
A2 is currently implemented for Intel SMP-compatible multi-processor systems (hyperthreading is supported) and Intel-compatible single-processor systems as well as for the
Strong-ARM/XScale processor. A2 can also run in several virtual machines such as Qemu, VMWare and Virtual PC 4.0 (Macintosh version only).
Of course this page is hosted on a server running A2.
If you are interested in using A2, please have a look at the Oberon Community Platform.
