A Methodology for Automated Design of Hard-Real-Time Embedded Streaming Systems
"... Abstract—The increasing complexity of modern embedded streaming applications imposes new challenges on system design-ers nowadays. For instance, the applications evolved to the point that in many cases hard-real-time execution on multiprocessor platforms is needed in order to meet the applications ’ ..."

, the design time must remain acceptable. This requires the development of novel systematic and automated design methodologies driven by the aforementioned challenges. In this paper, we propose such a novel methodology for automated design of an embedded multiproces-sor system, which can run multiple hard-real-time
Using UML for modeling complex real-time systems
, 1998
"... The embedded real-time software systems encountered in applications such as telecommunications, aerospace, and defense typically tend to be large and extremely complex. It is crucial in such systems that the software is designed with a sound architecture. A good architecture not only simplifies cons ..."

The Time-Triggered Architecture
- PROCEEDINGS OF THE IEEE
, 2003
"... The time-triggered architecture (TTA) provides a computing infrastructure for the design and implementation of dependable distributed embedded systems. A large real-time application is decomposed into nearly autonomous clusters and nodes, and a fault-tolerant global time base of known precision is g ..."

An Optimal Design Flow for Hard Real-Time Streaming Systems
"... Abstract—In this paper, we address the problem of auto-mated design of hard real-time embedded streaming systems. To this end, we introduce the notion of optimal design flow. An optimal design flow is one that accepts, as input, a set of hard real-time streaming programs, and then produces in a full ..."

Real-time and embedded systems
"... Scenario-based design exploits the time-varying execution behavior of applications by dynamically adapting the system on which they run. This is a particularly interesting design methodology for media applications with soft realtime constraints such as decoders: frames can be classified into scenari ..."

Scalable routing strategies for ad hoc wireless networks
- IEEE JSAC
, 1999
"... In this paper, we consider a large population of mobile stations that are interconnected by a multihop wireless network. The applications of this wireless infrastructure range from ad hoc networking (e.g., collaborative, distributed computing) to disaster recovery (e.g., fire, flood, earthquake), l ..."

), law enforcement (e.g., crowd control, search-and-rescue), and military (automated battlefield). Key characteristics of this system are the large number of users, their mobility, and the need to operate without the support of a fixed (wired or wireless) infrastructure. The last feature sets this system
Design Space Exploration for Real-Time Embedded Stream
"... We present a framework for rapidly exploring the design space for stream processors in real-time embedded systems. Stream processors are high performance digital signal processors with clusters of arithmetic units. There is a trade-off between the number of arithmetic units in a cluster of a stream ..."

1 Application Scenarios in Streaming-Oriented Embedded System Design
"... Abstract—In the past decade, real-time embedded systems became more and more complex and pervasive. From the user perspective, these systems have stringent requirements regarding size, performance and energy consumption, and due to business competition, their time-to-market is a crucial factor. Ther ..."

We furthermore briefly describe our automated scenariobased design trajectory for reducing
Object-Oriented Specification and Design of Embedded Hard Real-Time Systems
- Proceedings of the ICDA2000
"... The approach presented in this paper is a contribution to combine well established methodologies in software engineering, namely object-orientation, with novel co-simulation techniques for real-time HW/SW system simulation, and new synthesis techniques based on the HW-semantics of object-oriented HW ..."
