Étude des performances dans les systèmes embarqués, entre simulation numérique et solution équationnelle

Saturday 1 January 2011

Years: 2009 (Master 1 internship)
Co-supervisor: Karine Altisen
Subject: Étude des performances dans les systèmes embarqués, entre simulation numérique et solution équationnelle
Abstract:

Current embedded systems are getting more and more complex, whereas their developement cycles are getting shorter and shorter. During the industrial design phase, engineers expect an approximation of the system’s performances, before any physical prototype has been made, and while the system has only a high level abstraction description. In order to answer to the growing complexity of systems, an analysis framework has been introduced : the Modular Performance Analysis (or MPA). In this framework, systems are represented by components which communicate through channels with infinite event flows. This framework is strongly linked with an analytical method : the Real-Time Calculus (or RTC). Recent work aim at connecting RTC to other formalisms which allow to describe abstract systems (named computational models), such as the language Lustre and automata.

After describing the main ideas of RTC and of analysis methods on computational models, this report rises the issue of the relevance of RTC to describe abstractions of event flows in the MPA framework, and it proposes a new abstraction to describe those event flows, with a method allowing to determine the transformation of an event flow described by this abstraction, by a modular system. Finally, this report describes a programm which implements this method using the analysability power of NBac.
