Reconfigurable computer architectures for dynamically adaptable avionics systems

Computing and processing capabilities from reconfgurable computer architectures (RCAs) can provide high-integrity avionics systems with outstanding effciency and effectiveness, as they do in other domains. However, they are still underexploited in many applications. The main driver of this situation is that devices implementing such architectures are too advanced and powerful for the system's needs. The situation in avionics is even worst, because there are just few certifable RCA devices for aerospace. In addition, the fexible nature of RCAs incurs high costs and risks along the system development life cycle (certifcation processes). This article reviews existing methodologies and technologies for RCAs with a strong emphasis on computing granularity and agile management of resources.
