Towards an Aspect Oriented Language Compliant with Real Time Constraints

The Aspect-Oriented Programming (AOP) supports the modularization of concerns that cut across the implementation of a software application to avoid scattering and tangling. We focus on the integration of aspect-oriented paradigm in the development of real-time systems. The AOP is based on the weaving process to automatically integrate segments of code created separately into the application. In the context of real-time systems, this can endanger determinism by including constructs that may violate real-time constraints beyond the control of the developer. In this paper, we study and test the AspectAda language, an existing aspect mechanism, in order to adapt and modify it to respect real-time constraints. We are interested studying this language´s grammar, Runtime and especially weaving operation. Finally, we extract its limits and define our solutions to adapt it to support real time constraints.
