AADL

Bruno Bouyssounouse — 2006-07-05T11:34:48Z

The SAE AADL is an extensible architecture analysis and design language for embedded and real-time systems.

The core language provides a precise semantic specification for modeling task and communication architectures and their mapping onto distributed execution platforms.

What AADL can do

Represent embedded systems as component-based system architecture
Model component interactions as flows, service calls, and shared access
Model task execution and communication with precise timing semantics
Model execution platform and specify application binding
Represent operational modes and fault tolerant configurations
Support component evolution and large-scale development
Accommodate analyses such as reliability &safety- criticality through extensions

What are the benefits

Prediction and validation of runtime characteristics such as availability, timeliness, security;
Validated system architectures and implementations;
Improved development process through single annotated architecture model;
AADL as part of a model-based engineering enterprise solution;
AADL models as deliverables and subcontractor management;
interoperability & integration of commercial and in- house tools.

UML 2.0

Ulrike Woern — 2006-07-04T16:07:00Z

The Unified Modeling Language (UML) is a non-proprietary, object modeling and specification language used in software engineering. UML is a general-purpose modeling language that includes a standardized graphical notation that may be used to create an abstract model of a system, sometimes referred to as the UML model.

UML may be considered as an extensible modeling language since it offers a profile mechanism to customize the language.

If a concept you need is not present in the base language, you may introduce it by defining a stereotype. The semantics of extension by profiles has been improved with the UML 2.0 major revision.

30. EURASIP

The EURASIP Journal on Embedded Systems (EURASIP JES) serves the large community of researchers and professional engineers who deal with the theory and practice of embedded systems, particularly encompassing all practical aspects of theory and methods used in designing homogeneous as well as heterogeneous embedded systems that combine data-driven and control-driven behaviors.

Coverage includes:

complex homogeneous and heterogeneous embedded systems,
specification languages and tools for embedded systems
modeling and verification techniques, hardware/software trade-offs and codesign
new design flows
design methodologies and synthesis methods
platform-based design
component-based design
adaptation of signal processing algorithms to limited implementation resources
rapid prototyping
computing structures and architectures for complex embedded systems
real-time operating systems
methods and techniques for the design of low-power systems
interfacing with the real world
novel application case studies and experiences

Example applications include:

wireless and data communication systems
speech processing, image and video processing
digital signal processing applications
control and instrumentation.
