UML-Based Analysis of Power Consumption for Real-Time Embedded Systems

IPS-HAG11

The complexity of embedded systems has risen significantly in the last years. The model based development approach helped to keep an overview over the development and over the fulfillment of non-functional properties, as it is possible to capture and analyze the scheduling using UML development models. Other aspects, e.g. the power consumption, are not considered in development models, modelling languages, and analysis support based on development models.

The common approach is to measure the consumption at the end of the development, but there is no tool support for earlier phases analysis. We present a UML profile for power/energy consumption and a simple algorithm to analyze the power consumption based on an UML model extended with our profile. As more power awareness could result in losing real-time constraints, we consider both aspects, real-time scheduling and power awareness, and present a method to bring both non-functional properties and their analyses in context. Additionally, we present an approach to find a task configuration for a dynamic voltage scaling system that satisfies all real-time requirements, but is most power efficient.
