PARLOT Analysis and Partitioning of Energy Efficient Real-Time Systems (nur in Englisch verfügbar)

Motivation

Embedded systems have become an integral part of our daily lives. Mobile phones, the Internet, Anti Lock Brake Systems and aktive chassis - the number of applications for integrated embedded systems are limited only by our imagination. Increasingly complete systems are integrated on a single chip while demands for performance and smaller product cycles require new design methodologies for embedded systems. Project Parlot is aimed towards the development and research of the fundamentals of future system synthesis tools.

Ziele

Modern embedded systems consist of data flow oriented and event oriented components. For the analysis of these systems it is necessary to research the models and algorithms, that are capable of merging the concpets of dataflow oriented and the event oriented domain. For this reason a new model for the performance analysis of distributed real-time systems, the event dependency graph, is developed and its properties researched. The idea is to extend the concept of classical task graphs with simple data dependencies by the concept of event streams. Unlike todays state of the art should not only be used to describe the activation of tasks, but every communications between tasks or modules. Beyond that, the timing behavior of a task itself should be described by event streams.

 

New mathematical methods are developed within this project, that allow the computation of a resulting event stream from an activating stream. When all event densities have been calculated, matching partitionien criteria are to be found.
