Using improved resource interfaces to formally describe adaptability in embedded systems

Abstract

In embedded systems, timing and resource utilization are vital aspects, having impacts on the deployed software. In this paper, an extensible formal framework for modeling of resource usage and adaptability of software components is introduced. The formalism explicitly supports modeling resources of various types and in different ways; and the timing requirements that applications have. The models can be used as a basis for quantitative analysis, and in the extension as a basis for system synthesis. An example of usage of the formalism is given.
