Workshop on Adaptive and Reconfigurable Embedded Systems

Adaptive systems can respond to environmental changes including hardware/software defects, resource changes, and non-continual feature usage. As such, adaptive systems can extend the area of operations and improve efficiency in the use of system resources. However, adaptability also incurs overhead in terms of system complexity and resource requirements. For example, an adaptive system requires some means for reconfiguration. These means and their mechanisms introduce additional complexity to the design and the architecture, and they also require additional resources such as computation, power, and communication bandwidth. Consequently, adaptive systems must be diligently planned, designed, analyzed, and built to find the right tradeoffs between too much and too little flexibility.

The issue is how to provide the adaptability to the application, because it affects all aspects of the development process (e.g., capturing, methodologies, modeling, analysis, testing, and implementation), the chosen system technologies (e.g., computation and communication models, interfaces, component-based design, programming languages, dependability, and design patterns) and the system itself (e.g., operating system, middleware, network protocols, and application frameworks).

In many systems, flexibility and the resulting tradeoffs is usually ignored until a very late stage. Many try to retrofit existing prototypes, middleware, operating systems, and protocols with concepts and means for flexibility such as run-time system reconfiguration or reflexive diagnostics and steering methods. Such retrofitting typically leads to disproportionate overhead, unusual tradeoffs, and in general it leads to less satisfactory results.

Purpose of the workshop

The purpose of the workshop is to discuss new and on-going research that is centered on the idea of adaptability as first class citizen and consider the involved tradeoffs. The workshop will provide an open forum to discuss ideas and approaches, and intends to give the attendees a chance to discuss them in a relaxed environment. The target audience includes people from academia, tool vendors, system suppliers, and users in industry interested in the all aspects of the mentioned topics. The workshop will be based on presentations of selected works with sufficient time for feedback from the audience and discussions. We encourage all the prospective participants to submit short papers, workin-progress reports, or position papers.
