DECOS

Hermann Kopetz — 2006-07-05T15:10:07Z

DECOS Dependable Embedded Components and Systems is an integrative project that will develop the basic enabling technology to move from a federated distributed architecture to an integrated distributed architecture in order to reduce development, production and maintenance cost and increase the dependability of embedded applications in many application domains. DECOS plans to develop technology invariant software interfaces and encapsulated virtual networks with predictable temporal properties such that application software can be transferred to a new hardware and communication base with minimal effort (legacy re-use). The DECOS methodology and the tools will be evaluated by building three applications in the automotive, aerospace and control domain, respectively. DECOS builds on the substantial results of previous European research projects (NextTTA, FIT, TTA, SETTA, RISE, X-By-Wire, PDCS, DEVA, DSOS). The components and tools developed within DECOS will cover: cluster design, middleware and code generators, validation and certification as well as systems-on-a-chip (SoCs) for high dependability applications.

DECOS aims at maintaining and significantly enhancing Europe's pre-eminent competitive position in technology and application areas and will open an emerging market for tool suppliers. The integrating effect of the project will result in continued future cooperation between the partners and will create the basis for an emerging technology platform for dependable embedded systems.

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.

DO-178B

Ulrike Woern — 2006-07-04T15:33:01Z

DO-178B, Software Considerations in Airborne Systems and Equipment Certification is a standard for software development. The standard was developed by RTCA and EUROCAE. The FAA accepts use of DO-178B as a means of certifying software in avionics.
