TITLE: Physical Real-Time Computing

by Lothar Thiele

ABSTRACT: An important class of real-time systems interact with, sense, and respond to the world around them. Much of the research effort is related to understanding interference between concurrent activities due to shared resources, minimizing and limiting interference through hardware and software designs, and reducing resource usage while providing guarantees. On the other hand, this class of real-time systems is typically deeply embedded in a physical environment. The challenges for providing guaranteed responses within certain time constraints go beyond the typical keywords such as non-deterministic and time-varying processing requirements, interference on computational, communication and storage components.

The talk will focus on models and methods for providing timing guarantees for systems that are subject to interference from the physical environment in which they are embedded. Examples include non-deterministic communication behavior in low-power networks, changes in ambient temperature, and sustainable energy supply through energy harvesting. We will discuss modeling approaches, analysis, and design methods to limit or even avoid these types of interference while still providing usable low-power systems. Finally, we will discuss limitations and practical experiences with the described design principles. Special emphasis will be placed on their use in environmental monitoring in high alpine areas and automatic control.
