Java still is a rather exotic language in the field of real-time and particularly embedded systems, though it could provide productivity and especially safety and dependability benefits over the dominating language C. The reasons for the lack of acceptance of Java in the embedded world are the high resource consumption caused by the Java runtime environment(More)
The automotive industry has recent ambitions to integrate multiple applications from different micro controllers on a single, more powerful micro controller. The outcome of this integration process is the loss of the physical isolation and a more complex monolithic software. Memory protection mechanisms need to be provided that allow for a safe coexistence(More)
There is hardware- and software-based memory protection that can improve the dependability of software systems. The two variants vary in the degree of protection and the amount and sites of overhead. The decision for a particular mechanism therefore highly depends on the application and deployment scenario. We propose a system suited for deeply embedded(More)
Offering many benefits in terms of productivity and reliability, Java is becoming an attractive choice for the field of embedded computing. However, its programming model that relies on the capabilities of just-in-time compilation limits the opportunities to generate highly optimized code in an ahead-of-time compiler. In the KESO project, a Java VM for(More)
Due to the reduction of structure sizes in modern embedded systems, tolerating soft errors presenting itself as bit flips becomes a mandatory task even for moderate critical applications. Accordingly, software-based fault tolerance mechanisms recently gained in popularity and a multitude of approaches that differ in the number and frequency of tolerated(More)
The field of embedded systems is experiencing a trend towards an advancing degree of integration. As microprocessors become increasingly powerful, more and more applications are run as tasks on a single microcontroller instead of being deployed separately on different chips. This development brings along new challenges in terms of safety, security, and(More)
Modern cars contain a large number of diverse microcon-trollers for a wide range of tasks, which imposes high efforts in the integration process of hardware and software. There is a paradigm shift from a federated architecture to an integrated architecture with commonly used resources to reduce complexity, costs, weight and energy. AUTOSAR [3] is a system(More)
—Type-safe high-level languages such as Java have not yet found their way into the domain of deeply embedded systems, even though numerous attempts have been made to make these languages cost attractive. One major challenge that remains is the huge existing code base in many industries. Completely reengineering this code base is not viable for cost and time(More)
