Motivation

Auf dem Gebiet der Informatik haben wir nur eingeschränkte Möglichkeiten auf die Effizienz der Hardware direkt einzuwirken, bzw. sind abhängig von den Herstellern (bspw. von Mikrocontrollern). Um jedoch das volle Potential der uns gestellten Hardware auf Systemebene auszunutzen, benötigen wir ein tiefergehendes Verständnis über die Hintergründe, Prozesse und Mechanismen von Verlustleistungen in eingebetteten Systemen. Woher kommt die Verlustleistung, was passiert auf Hardware-Ebene, welche Mechanismen kann ich direkt/indirekt nutzen, welchen Tradeoff zwischen Flexibilität und Effizienz habe ich,... sind nur einige Fragen, welche in dieser Veranstaltung erarbeitet und diskutiert werden sollen.

Inhalte

Eine gute Übersicht, was genau in der Vorlesung vermittelt wird, bzw. wie die Vorlesung strukturiert ist, ist in der nachfolgenden Präsentation verdeutlicht:
teaser

Wer es noch etwas detaillierter haben möchte, findet in dem Paper Course: Energy Efficiency in Embedded Systems - A System-Level Perspective for Computer Scientists weitere Informationen und nützliche Angaben bezüglich Literatur etc.

Qualifikationsziele

Nach Abschluss dieses Moduls besitzen die Studierenden ein tiefergehendes Verständnis von Hard- uns Software-Mechanismen zur Bewertung und Entwicklung energieeffizienter eingebetteter Systeme.
