Preface to special issue on adaptive embedded systems

摘要

An embedded system is adaptive, if it can modify its behavior and/or architecture to changing conditions and requirements. This is increasingly important as the complexity and autonomy of embedded and cyber-physical systems increase. Adaptivity is a cross-cutting system characteristic that affects both hardware and software as well as modeling, architecture, and run-time support. An adaptive system is required to be able to dynamically respond to changing conditions and contexts and through this maintain or improve performance and resource utilization. The changes can involve changes in resource requirements, changing system objectives, and changing external conditions.
