Content

In the field of computer science, we have only limited possibilities to influence the efficiency of the hardware directly, or we are dependent on the manufacturers (e.g. of microcontrollers). However, in order to exploit the full potential of the hardware provided to us at the system level, we need a deeper understanding of the background, processes and mechanisms of power dissipation in embedded systems. Where does the power dissipation come from, what happens at the hardware level, what mechanisms can I use directly/indirectly, what is the tradeoff between flexibility and efficiency,.... are only some questions, which will be worked out and discussed in this course. In the lecture and the corresponding exercise the following contents will be taught:

• Motivation and power dissipation of semiconductors
• Power dissipation of digital circuits
• CMOS and its power consumption
• Power management in hardware and software (sleep modes, DVS, FS, undervolting)
• Energy efficient system design (applications)
• Energy Harvesting and Transiently Powered Computing (TPC)

The course is complemented by a project-based exercise in which aspects learned on an energy harvesting platform (AVR microcontroller) are put into practice.

Prerequisite

• Computer engineering (necessary)
• Programming skills in C (required)
• Computer architectures (recommended)
• High motivation and interest in the subject
