Time- and space-partitioned systems (TSP) … Time- and space-partitioned systems (TSP) are a current trend in safety-critical systems, most notably in the aerospace domain; applications of different criticalities and origins coexist in an integrated platform, while being logically separated in partitions. To schedule application activities, TSP systems employ a hierarchical scheduling scheme. Flexible (self-)adaptation to abnormal events empowers the survivability of unmanned space vehicles, by preventing these events from becoming severe faults and/or permanent failures. In this paper, we propose adding self-adaptability mechanisms to the TSP scheduling scheme to cope with timing faults. Our approach consists of having a set of feasible and specially crafted partition scheduling tables, among which the system shall switch upon detecting temporal faults within a partition. We also present the preliminary experimental evaluation of the proposed mechanisms. tal evaluation of the proposed mechanisms.
