Intercluster activity: Design for Adaptivity

An embedded hardware-software system is adaptive, if it can modify its behavior and/or architecture to changing conditions and requirements. Adaptivity is increasingly important as the complexity and autonomy of embedded systems increases. Adaptivity is a cross-cutting system characteristic that affects hardware and software as well as modeling, architecture, and run-time support.

  • High-Level Objectives  

    An embedded hardware-software system is adaptive, if it can modify its behavior and/or architecture to changing requirements. Adaptivity is increasingly important as the complexity and autonomy of embedded systems increases. Adaptivity is required both off-line at design-time and on-line at run-time.

  • Brief State of the Art 

    Adaptive resource management is primarily of interest in consumer electronics, industrial automation, and telecommunications. The majority of the activities are related to multimedia streaming, where multiple video and audio streams are common. It is not uncommon to have a desired system utilization that is well beyond 100 %. Designing the system for the worst-case scenario is not exonomically justified. Hence, adaptivity is needed in order to be able to dynamically tradeoff the quality of the activities.

  • Main Research Trends  

    Real-time systems constitute a notable share of today’s embedded computers that needs special attention. The design of robust and fault-tolerant real-time systems is a highly active research area that has produced numerous approaches for evaluating and increasing system robustness against selected fault scenarios.

  • Industrial Sectors Impacted 

    The use of adaptive resource management is of particular interest for soft real-time applications, e.g., multimedia applications within consumer electronics systems and in telecommunications. Consumer electronics products range from miniature cameras and MP3 players to advanced media servers and large displays. Mainly driven by Moore’s law, the evolution in the CE industry is very fast. Utilizing available hardware and software resources in an optimal fashion is crucial both to save costs and to keep the competitive edge.
