Introduction
OCEOS is a pre-emptive real time operating system (RTOS) with a small memory footprint intended for hard real time systems that use the GR716 micro-controller [ref.].
It was developed by O.C.E. Technology with support from the European Space Agency (ESA) under project 4000127901/19/NL/AS.
This document describes the features and use of OCEOS, and details its behaviour and system calls.
