Model-based design of real time embedded application reconfiguration

Abstract

Maximizing the system output quality under resource constraints presents an inherent challenge in the design of RTES. To deal with this issue, scaling the application quality level through algorithmic or parameters tuning is an interesting adaptation mechanism since it permits to handle the complexity of modern embedded applications. Unfortunately, this adaptation mechanism is still under-explored by existing model-based design approaches. It is also not supported by the UML MARTE profile. Therefore, we propose in this chapter a model-based design of application reconfiguration using the MARTE standard. We define an additional package extending the Software Resource Modeling sub-profile. Then, in order to promote reusability of our proposed extension and facilitate its use by non-experts, we exploited it in the definition of a design pattern for an adaptation RTES decision making process. © 2015 Springer International Publishing.
