Embedded Systems Resources: Views on Modeling and Analysis

The conflicting requirements of real-time embedded systems, e.g. minimizing memory usage while still ensuring that all deadlines are met at run-time, require rigorous analysis of the system´s resource consumption, starting at early design stages. In this paper, we glance through several representative frameworks that model and estimate resource usage of embedded systems, pointing out advantages and limitations. In the end, we describe our own view on how to model and carry out formal analysis of embedded resources, along with developing the system.
