While Electronic Design Automation made the shift towards system design and high-level design methods keep on emerging, there is hardly any open framework which allows researchers to quickly prototype novel synthesis algorithms. We present System#, an open source system level design framework based on C#. System# tries to bridge the productivity gap by covering modeling, simulation, code transformations...
Vehicle-to-vehicle communication (V2VC) promises to be a next major step towards safe and efficient road traffic. This contribution presents a V2V communication system on FPGA-basis. It provides a flexible and modular hardware framework for various software-implemented V2V applications and routing algorithms. Exploiting the benefits of reconfigurable hardware the system manages to provide hardware...
FlexRay, the prospective real time bus system, will expand the successfully used CAN bus for automotive applications. Its functionalities cover an enhanced transfer rate, deterministic real time capabilities and a time- and event-triggered transmission segment. Its great flexibility comes for the price of a huge amount of configuration parameters. The parameter set of a configuration covers more than...
Todaypsilas vehicles include a complex network of programmable electronic control units with software components. A vehiclepsilas electric and electronic (EE) architecture has to be modeled in an early design phase to evaluate design alternatives. The tool PREEvision offers possibilities to model EE-architectures considering feature function networks, function networks, component networks as well...
While research and standardization in the area of car-to-X (C2X) communication gains interest steadily, realization and integration in on-board-units (OBU) becomes an issue. Lacking existing testbeds, the evaluation, test, and rapid prototyping of such systems relies on stimulation from simulated environments. We present an extension of an open-source traffic simulation to allow generation of C2X...
This paper proposes a method for measuring hardware configurations for trusted platforms based on field programmable gate arrays (FPGA). The proposed system setup allows for partial reconfiguration as well as full reconfiguration of FPGA devices that can be used additionally as trusted platforms. In the system, slots are defined for fast partial dynamic reconfiguration. Predefined IP blocks may be...
In order to overcome the logistical impediments caused during mass casualty disasters, we had proposed a new emergency response system based on a location aware wireless sensor network in our previous work. In this paper, we have implemented two new Bayesian filter based algorithms called improved range-based Monte Carlo patient localization and range-based unscented Kalman filter patient localization...
During emergency response to mass casualty disasters, one of the main logistic impediments faced by the On-site Organizational Chief (OOC) is to track the patients at the disaster site. We had proposed our previous work a new system based on a location aware wireless sensor network (WSN) to overcome these impediments and assist the responders in providing efficient emergency response. In this paper...
To get more information about oncoming road and traffic situations, exchange of data between cars is a large benefit. But relying on data obtained from other cars and hence sensors not under direct control of the system, guaranteeing trustworthiness and integrity of this data is of paramount importance. This creates the need for security measures for the data exchange which impose high computational...
We present an application tailored packed-based SoC communication system with one-hop communication between all entities, priority-based arbitration, broadcast and multicast support on a bus-shaped basis. It is located as a hybrid between NoC and bus approaches, closing the gap for mostly streaming-based systems with the need for highly flexible communication patterns and multicast messages that are...
In order to investigate the correlation between stress and cognitive performance, a mobile Body & Mind Monitoring System was implemented. This system has a modular design and contains different modules allowing a long time and noninvasive monitoring of physiological parameters of a test person in his every day life, for instance ECG, GSR, PPG, respiration and physical activity. The functionality...
Innovation in today's automobiles is mainly driven by electronic development. Standard infotainment devices delivered by car manufacturers offer services such as navigation, television, DVD, telephony and more. Especially in the last few years a trend can be recognized extending from these OEM specific solutions towards integration of consumer electronic devices such as iPods, cell phones or the like...
Reconfigurable architectures and NoC (network-on-chip) communication systems have introduced new research directions for technology and flexibility issues, which have been largely investigated in the last decades. Exploiting the flexibility of reconfigurable architectures, the run-time adap-tivity through run-time reconfiguration, opens a new area of research by considering dynamic reconfiguration...
Graphical modeling languages allow to specify structure and behavior of mixed hardware-and software-systems on high abstraction level and can be automatically rendered into deployable implementations. In this paper we extend a model-based development process by means to debug functionality specified using Matlab Stateflow models in its hardware-and software-implementation on the target system. The...
We extend a model based development approach for software components of embedded systems by a model based testing framework. We motivate by describing challenges a developer has to face when developing embedded software and present as a solution an UML-centric development approach. We introduce a testing framework that allows specification of test cases for UML class models using UML sequence- and...
An extension to a seamless, model-based development approach provides an architecture for debugging models that execute on target systems or in dedicated rapid-prototyping environments. During development, the ever-increasing design complexity of embedded systems frequently comes into conflict with cost, time-to-market, and quality. This complexity results from increasing functionality, the expanding...
Model based development based on different domain specific tools and graphical notations gains increasing importance in system design of embedded electronic systems allowing fast concept-oriented prototyping from model to code. This paper describes an extension to our seamless model based development approach: An architecture for debugging models that are executed on target systems or in dedicated...
Up to 70 electronic control units (ECU's) serve for safety and comfort functions in a car. Communicating over different bus systems most ECU's perform close loop control functions and reactive functions and have to fulfill hard real time constraints. Some ECU's controlling on board entertainment/office systems are software intensive, incorporating millions of lines of code. The challenge for the design...
