Nanosatellite On-Board Computer including a Many-Core Processor

Abstract:

Software fault tolerance techniques can be applied to multi or many-core processors benefitting of the multiplicity of cores. The MPPA Coolidge many-core processor developed by KALRAY (Grenoble, France) was selected in the frame of OVNIPROM1 project as a target for the implementation of the N-Modular Redundancy and M-Partitions (NMR-MPar) fault tolerance technique developed at TIMA. This paper describes the implementation of this technique applied to the MPPA processor for its use as the heart of a nanosatellite On-Board Computer (OBC) to deal with errors produced by radiation effects.
