Descripción
The current trend to use partitioned architectures in on- board spacecraft software requires applications running on the same computer platform to be isolated from each other both in the tempo- ral and memory domains. Memory isolation techniques currently used in Integrated Modular Avionics for Aeronautics usually require a Memory Management Unit (MMU), which is not commonly available in the kind of processors currently used in the Space domain. Two alternative ap- proaches are discussed in the paper, based on some features of Ada and state-of-the art compilation tool-chains. Both approaches provide safe memory partitioning with less overhead than current IMA techniques. Some footprint and performance metrics taken on a prototype imple- mentation of the most flexible approach are included.
