A Method for the Development of Platform Models in the Model Driven Architecture Context

The application of the Model Driven Architecture (MDA) approach to the design of embedded software based on Real-Time Operating Systems (RTOS) is encouraged by the fact that such software has a wide variety of platforms. In this way, the creation of methods for the development of platform models that meet such diversity of platforms is necessary. This study proposes a method called PM-MDA for the development of platform models that design embedded software based on RTOS in the context of MDA. In addition, this study defines the swxRTOS metamodel, a UML 2.0 profile for RTOS based on embedded software design. Such profile defines a set of stereotypes to describe Platform Models (PMs) and is intended to generically describe the services provided by a given embedded system platform of the RTOS. This profile promotes the creation of Platform Models, which will be used as input parameters in the model transformation. Due to the inherent complexity in embedded software design and the existence of a wide variety of platform models, new methods that support the development of such software become crucial.
