Description

The UML modeling language has been extended by the OMG consortium to support model-driven development of real-time and embedded application. This extension has been defined via a UML2

Core

The core part of MARTE is made of five chapters. * CoreElements; * Non-Functional Properties: This chapter specifies some notations to define various kinds of values related to physical quantities: time, mass, energy; * Time: This chapter defines a rich model of time that supports both the definition of physical and logical time properties;. It comes with a companion language called CCSL defined as an annex. * Generic Resource Modeling: This chapter offers extensions required to model a general platform for executing real-time embedded applications; * Allocation Modeling: Finally, this chapter defines a notion of allocation to allocate application elements onto the execution platforms. A specific attention has been given to maintain compatibility with SysML allocation mechanism.
