During the last two years, EDISOFT’s RTEMS CENTRE team, jointly with the European Space Agency and with the support of the worldwide RTEMS community, have been developing an activity to facilitate the qualification of the real-time operating system RTEMS (Real-Time Operating System for Multiprocessor Systems).
This paper intends to give a high level visibility of the progress and the results obtained in the RTEMS Improvement activity. The primary objective of the project is to improve the RTEMS product, its documentation and to facilitate the qualification of RTEMS for future space missions, taking into consideration the specific operational requirements. The sections below provide a brief overview of the RTEMS operating system and the activities performed in the RTEMS Improvement project, which includes the selection of API managers to be qualified, the tailoring process, the requirements analysis, the reverse engineering and design of the RTEMS, the quality assurance process, the ISVV activities, the test campaign, the results obtained, the criticality analysis and the facilitation of qualification process.
