Towards UML 2 Extensions for Compact Modeling of Regular Complex Topologies.

The MARTE RFP (Modeling and Analysis of Real-Time and Embedded systems) was issued by the OMG in February 2005. This request for proposals solicits submissions for a UML profile that adds capabilities for modeling Real Time and Embedded Systems (RTES), and for analyzing schedulability and performance properties of UML specifications. One of the particular request of this RFP concerns the definition of common high-level modeling constructs for factorizing repetitive structures, for software, hardware and allocation modeling of RTES. We propose an answer to this particular requirement, based on the introduction of multi-dimensional multiplicities and mechanisms for the description of regular connection patterns between model elements. This proposition is domain independent. We illustrate the use of these mechanisms in an intensive computation embedded system co-design methodology. We focus on what these factorization mechanisms can bring for each of the aspects of the co-design: application, hardware architecture, and allocation. [ABSTRACT FROM AUTHOR]
