The determination of upper bounds on execution times, commonly called worst-case
execution times (WCETs), is a necessary step in the development and validation process for …

Infinite element schemes for unbounded wave problems are reviewed and a procedure is
presented forassessing their performance. A general computational scheme is implemented …

We address power-aware scheduling of periodic tasks to reduce CPU energy consumption
in hard real-time systems through dynamic voltage scaling. Our intertask voltage scheduling …

The high power consumption of modern processors becomes a major concern because it
leads to decreased mission duration (for battery-operated systems), increased heat …

In this paper we address power-aware scheduling of periodic hard real-time tasks using
dynamic voltage scaling. Our solution includes three parts:(a) a static (off-line) solution to …

Power efficient design of real-time systems based on programmable processors becomes
more important as system functionality is increasingly realized through software. This paper …

Several syntactic-based automatic worm signature generators, eg, Polygraph, have recently
been proposed. These systems typically assume that a set of suspicious flows are provided …

Dynamic voltage and frequency scaling (DVFS) has been widely used to manage energy in
real-time embedded systems. However, it was recently shown that DVFS has direct and …

In this article we give an overview of the worst-case execution time (WCET) analysis
research performed by the WCET group of the ASTEC Competence Centre at Uppsala …

Ever increasing embedded system design complexity combined with a very tight time-to-
market window has revolutionized the embedded-system design process. The concurrent …
