Summary

The OCE Technology OCEOS is a real-time pre-emptive fixed priority operating system that can be used in applications that require European Cooperation for Space Standardization Category B or ISO 26262 standards.

It has a small memory footprint (<10 kBytes), requires only one system stack rather than a stack for each task, and provides support for precisely timed data outputs independent of task scheduling. OCEOS supports applications running on SPARC & ARM-based hardware.

OCEOS supports applications running on SPARC & ARM-based hardware. The support of the European Space Agency (ESA) in developing OCEOS is acknowledged. It supports up to 254 tasks with up to 15 current execution instances of each task, allowing one task to service multiple units of the same type. Each task has a fixed priority and more than one task may have the same priority.

Key features

Fixed priority pre-emptive scheduling
Based on Stack Resource Policy - unbounded priority inversion, chained blocking, and deadlocks cannot occur.
Single stack rather than separate stack for each task
Small code footprint ( <10 kBytes for scheduling and mutex)
Mutex, Counting Semaphore, and Data Queue support
High-precision timed actions (data output and task start)
Supports SPARC and ARM Cortex-M single-core targets
Ideal for Cobham-Gaisler GR716 and Arm Cortex-M applications
DMON debug tool support (execution timeline, CPU usage)
Support & ISVV services available from OCE
Gold standard customer support package
Developed to ECSS Category B and ISO 26262 standards
Developed in cooperation with European Space Agency (ESA)
