Rate-Adaptive Tasks: Model, Analysis, and Design Issues

Buttazzo, Giorgio C. ; Bini, Enrico LU and Buttle, Darren (2014) 2014 Design, Automation and Test in Europe Conference
Abstract
In automotive systems, some of the engine control tasks are triggered by specific crankshaft rotation angles and are designed to adapt their functionality based on the angular velocity of the engine. This paper proposes a new task model for specifying such a type of real-time activities and presents an approach for analyzing the system feasibility under dynamic scheduling for different scenarios. A design method is also discussed to determine the most suitable switching speeds for adapting the functionality of tasks without exceeding a desired utilization. Finally, a number of research directions are highlighted to extend the current results to more complex and realistic scenarios.
