A MDD Approach for RTOS Integration on Valid Real-Time Design Model

Abstract

The transition from the design model to the implementation model is a critical phase in Real-Time Embedded Systems development process. Indeed, this model must conserve functional and non-functional requirements of the design model on the target execution platform. In this paper, we propose a two-steps approach based on an explicit description of two types of platform: the abstract platform used at the design level to validate the different design choices, and the concrete execution platform. The first step consists in feasibility tests whose role is to help the designer detecting the potential refinement problems. The second step is a mapping step that ensures the compliance of the implementation model with the design model taking into consideration the characteristics of the target execution platform.
