Grain-oriented computer architectures for dynamically-reconfigurable avionics systems

• Current RCAshave been reviewed with a strong emphasis on a full range of granularity and dynamic resource management at the grain level. • A good argument for having an effective control at the smallest reconfigurable unit in order to end up in efficient energy use on RCAshas been discussed. • The above hypothesis has led to classify and compare existing reconfigurable computer technologies in order to identify missing RCA approaches of a granularity-based spectrum. • An overview and a grain-based classification of existing RCAshave been presented. This has revealed technological gaps based on what current RCAscan provide, and what is needed in terms of dynamic reconfiguration of grain-oriented computer architectures for avionics systems. • UAVshave been taken into account as a good candidate to apply the RSA. In addition, a hybrid DRCAwhich implementation is proposed to be made by a programing language combined with a programmable hardware device has been proposed as an alternative for the RCA spectrum.
