In real-time systems response to a request from a controlled object must be correct and timely. Any late response to a request from such a device might lead to a catastrophy. The possibility of a task overrun, i.e., missing the deadline for completing a requested task, must be checked and removed during the design of such systems. Safe design of real-time systems running periodic tasks under th...

There is an increasing need for today’s autonomous systems to collaborate in real-time over wireless networks. These systems need to interact closely with other autonomous systems and function under tight timing and control constraints. This paper concerns with the modeling and quality assurance of the timing behavior of such network embedded systems. It builds upon our previous work on run-tim...

Java applets run on a Virtual Machine that checks code integrity and correctness before execution using a module called the Bytecode Verifier. Java Card technology allows Java applets to run on smart cards. The large memory requirements of the verification process do not allow the implementation of an embedded Bytecode Verifier in the Java Card Virtual Machine. To address this problem, we propo...

Java applets run on a Virtual Machine that checks code’s integrity and correctness before execution using a module called Bytecode Verifier. Java Card technology allows Java applets to run on smart cards. Large memory space requirements of the verification process do not allow the implementation of a Bytecode Verifier embedded in the Java Card Virtual Machine. To address this feasibility proble...

This paper presents an industrial-strength CAD system for logic optimization, technology mapping, and formal verification of synchronous designs. The new system, Magic, is based on the code of ABC that has been improved by adding industrial requirements. Distinctive features include: global-view optimizations for area and delay, scalable sequential synthesis, the use of white-boxes for instance...

Monitoring in embedded system software can have several uses, ranging from system characterization to run-time verification (RV). Traditional monitoring techniques require code instrumentation, imposing an overhead on system execution both in performance and timeliness. In real-time systems this is exarcebated by the need of new worst-case execution time estimation and schedulability analysis. ...

The accuracy levels achieved by state-of-the-art Speaker Verification systems are high enough for the technology to be used in real-life applications. Unfortunately, the transfer from the lab to the field is not as straight-forward as could be: the best performing systems can be computationally expensive to run and need large speaker model footprints. In this paper, we compare two speaker verif...

Following the vision of the Internet of Things, physical world entities are integrated into virtual world things. Things are expected to become active participants in business and social processes. Then, the Internet of Things could benefit from the Web Service architecture like today’s Web does, so Future service-oriented Internet things will offer their functionality via service-enabled inter...

When specifying system requirements, we want a language that can express the requirements in the simplest and most intuitive form. Although the MaC system provides an expressive language, called MEDL, it is generally awkward to express certain features like temporal ordering of complex events, timing constraints, and frequencies of events which are inherent in safety properties. MEDL-RE extends...
