Much effort has been undertaken to employ different aspects of UML for multiple domains, mainly in the area of software systems. Considering the area of electronic design automation, however, we currently see only very few approaches which investigate UML for hardware design and hardware/software co-design. We present an approach for executable UML closing the gap from system specification to its model-based execution on reconfigurable hardware. For this purpose, we present our abstract execution platform (AEP), which is based on a virtual machine running an executable UML subset for embedded software and reconfigurable hardware. This subset combines UML 2.0 classes, state-machines and sequence diagrams for a complete system specification. We describe how these binary encoded UML specifications can be directly executed and give the implementation of such a virtual machine on a Virtex II FPGA. Finally, we present evaluation results comparing the AEP implementation with C code on a C167 microcontroller.}}, author = {{Schattkowsky, Tim and Müller, Wolfgang and Rettberg, Achim}}, booktitle = {{Proceedings of DATE’05}}, isbn = {{0-7695-2288-2}}, keywords = {{Hardware, Unified modeling language, Virtual machining, Object oriented modeling, Field programmable gate arrays, Java, Microcontrollers, Embedded software, Real time systems, Documentation}}, publisher = {{IEEE}}, title = {{{A Model-Based Approach for Executable Specification on Reconfigurable Hardware}}}, doi = {{10.1109/DATE.2005.20}}, year = {{2005}}, } @inproceedings{39030, abstract = {{StateCharts are well accepted for embedded systems specification for various applications.

We introduce a UML Virtual Machine, which directly executes sequence diagrams, which are embedded into hierarchically structured state transition diagrams. Whereas state diagrams are directly executed as Embedded State Machines (ESMs), sequence diagrams are translated into UVM Bytecode. The final UVM execution is performed by the interaction of the ESM and the Bytecode Interpreter. Due to our completely model- based approach, the UVM runtime kernel is easily adaptable and scalable to different scheduling and memory management strategies.}}, author = {{Schattkowsky, Tim and Müller, Wolfgang}}, booktitle = {{Proceedings of ISNG 05}}, keywords = {{UML, Executable Models, Hardware/Software Co-design, Virtual Machine, Embedded Systems}}, title = {{{A UML Virtual Machine for Embedded Systems}}}, year = {{2005}}, } @inproceedings{39032, abstract = {{Executable UML models are nowadays gaining interest in embedded systems design.

However, fully featured UML 2.0 State Machines may contain a broad set of features with complex execution semantics that differ significantly from other StateChart variants. This makes their direct execution complex and inefficient. In this paper, we demonstrate how such state machines can be represented using a small subset of the UML state machine features that enables efficient execution.
