EUROS RTOS

EUROS is a real-time operating system that takes into consideration the requirements in the embedded field by

minimal memory requirements,
short response times,
flexible communication mechanisms and
a large set of available drivers and protocol stacks.

EUROS is suitable for nearly all common CPU architectures. The well-proven EUROS implementation is the basis for adaptation to any type of micro-controller.
The modular and hardware independent design opens up
a wide application range:

Embedded controllers
Boards systems
Automation devices
Personal computers

EUROS (Enhanced Universal Realtime Operating System) is a professional, multitasking capable operating system suitable to equip any devices.

The real time operating system EUROS...

can be used for a wide range of applications because of its modular and hardware-independent concepts.
is characterized by short response times, robustness and flexibility.
allows customization of the operating system.
is ROMable.
is a hardware-independent software platform. The base for EUROS versions for different microprocessors is a well-tested.
implementation in the C language.
implements a powerful driver interface which operates on a hardware abstraction level allowing for the highest possible driver portability. A number of device drivers are available.
carries your application into the future: new developments of hardware are covered by the Microkernel. More powerful chip versions can be used while leaving the application unchanged.
hides hardware details from the software developer. EUROS initializes chips and supports interrupt handling. Access to hardware is performed by Port Drivers.
allows multitasking by utilizing the specific characteristics of a certain chip architecture.
runs on IBM-compatible PCs. The PC is used as a development system and as a test system. Applications can be developed and tested on the PC. Application development can start even before the actual target hardware is available.
allows access to the Internet. Remote monitoring and remote control can be realized with a HTTP server.
opens up the possibility of Java in real-time applications. With the virtual machine EUROSvm Java applications can be run directly from ROM or Flash memory.
EUROSvm is currently available as a pilot implementation on the PowerPC.
is offered at a moderate price normally on buy-out basis. EUROS harmonizes the efforts aiming in establishing a uniform operating system.

Technical features

Task management:

Unrestricted number of tasks.
Priority controller scheduling (256 priority levels), optionally combined with time slicing (round-robin).
Priorities can be changed dynamically.
Deterministic behavior.
Extremely short task switch times.

Task synchronization and task coordination:

Semaphores
Event flags
Signals
Mailboxes
Pipes

Memory Management:

Megapools
Memorypools
Fixed-Sized-Buffers
Shared memory.

Other services:

Console services
Bit processing
Watchdogs
Interrupt services (prologs, state transitions)
Object management

Run-time coordination with the operating system:

Synchronous system calls (wait for completion)
Asynchronous system calls (parallel execution)
Multiple wait
Time delayed system calls

Comprehensive driver interface:

All services of the I/O system and all coordination mechanisms are available for all drivers without extra effort by the driver implementer.
Services like task coordination, request queue management and time-out handling are performed by the I/O system. Implementing a driver is reduced to programming the device-dependent functions only.

Code size (scalable operating system):
