Extending the Path Analysis Technique to Obtain a Soft WCET

Authors: Paul Keim, Amanda Noyes, Andrew Ferguson, Joshua Neal, and Christopher Healy

Published in: OASIcs, Volume 10, 9th International Workshop on Worst-Case Execution Time Analysis (WCET'09) (2009)

Abstract
This paper discusses an efficient approach to statically compute a WCET that is "soft" rather than "hard". The goal of most timing analysis is to determine a guaranteed WCET; however this execution time may be far above the actual distribution of observed execution times. A WCET estimate that bounds the execution time 99% of the time may be more useful for a designer in a soft real-time environment. This paper discusses an approach to measure the execution time distribution by a hardware simulator, and a path-based timing analysis approach to derive a static estimation of this same distribution. The technique can find a soft WCET for loops having any number of paths.

Accounting system for heterogeneous IP-networks (IPNA) implemented at Kaiserslautern University

Authors: Brian Worden, Claudia Baltes, Inga Scheler, Paul Müller, and Hans Hagen

Published in: Dagstuhl Seminar Proceedings, Volume 9211, Visualization and Monitoring of Network Traffic (2009)

Abstract
This paper describes an accounting system (IPNA) for heterogenous IP-networks with arbitrary topologies implemented at the university of Kaiserslautern. The produced data volume per unit is numerated. The collected data is stored in a database and offers different analysis possibilities. The results can be visualized and adapted to the users requirements. The main effort was to build a data traffic quota system for single units as well as groups of devices that also report exceeded quotas. The system itself only observes the network traffic. Interfaces offer tools to interact with the network. The IPNA consists of a back-end for the data- acquisition and -preparation and a front-end for configuration and visualization tasks including quality control.
