• discuss design space and associated embedded systems design methods
• name control and feedback control systems' core concepts
• characterise the fundamental digital signal processing algorithms

Methodological competence
The students:

• design and develop embedded feedback control systems with modelling tools
• implement an embedded hardware-/software system according to a given specification
• analyze various specification languages according to different properties

Social competence
The students:

• implement solutions to given problems in teams
• present results of computer science problems to groups
• organize themselves as a team to solve a larger problem using project management methods

Self-competence
The students:

• acknowledge the limits of their ability to cope with pressure during the implementation process of systems
• solve excercises self-responsibly

Embedded systems support complex feedback problems, control problems and data processing tasks. They have an important value creation potential for telecommunications, production management, transport and electronics. The functionality of embedded systems is realised by the integration of processors, special hardware and software. The embedded systems design is influenced by the heterogeneity of system architectures, the complexity of systems and technical and economic requirements. This module gives an overview of embedded systems and their design. The process of digital signals is especially important for telecommunications and multimedia. For this purpose, the module introduces digital signal processing algorithms. The principles of feedback control are introduced by exemplary transport applications. Subsequently, the module provides the specifications and language characteristics of the embedded system design. For this purpose, graphical data-flow modelling languages (for instance Simulink) and control-flow specifications (for instance State Charts) are presented. The module closes with the concepts of possible architectures and communication models. Hands-on exercises with the tools Matlab/Simulink/StateFlow support the module contents.

This module is compulsory for students who are specialising in "Eingebettete Systeme und Mikrorobotik". Associaltes with the modules:
In the module "Eingebettete Systeme II" additonal relevant topics such as design processes, HW/SW-Partitioning, High-Level-Synthesis and Hardware discription languages are discussed. The modules Eingebettete Systeme I und II offer cross-references to the module "Rechnerarchitektur", "Realzeitbetriebssysteme" and semantic orientated modules of theoretical computer science. It is possible to enhance the knowledge of embedded systems design by attending the modules "System Level Design" and "Low energy System Design".

At the end of the semester
