the safety of software-based control systems plays an essential role in a vast number of applications. SynTACS is a tool that generates a framework for controller supervision, which enforces safety during runtime by utilizing the supervisory control theory of Ramadge and Wonham. In this paper, the results of a user study are presented in which it was investigated how far discrete-event systems, the underlying modeling formalism, are suitable to express safety requirements. Further, the usability of the tool was evaluated. In the second part, several concepts are introduced to support use cases that require real-time controllers due to unstable processes. Finally, two case studies are presented to show the applicability of boththe tool and the new concepts.

real-time 3D space understanding is becoming prevalent across a wide range of applications and hardware platforms. To meet the desired Quality of Service (QoS), computer vision applications tend to be heavily parallelized and exploit any available hardware accelerators. Current approaches to achieving real-time computer vision, evolve around programming languages typically associated with High Performance computing along with binding extensions for OpenCL or CUDA execution. Such implementations, although high performing, lack portability across the wide range of diverse hardware resources and accelerators. In this paper, we showcase how a complex computer vision application can be implemented within a managed runtime system. We discuss the complexities of achieving high-performing and portable execution across embedded and desktop configurations. Furthermore, we demonstrate that it is possible to achieve the QoS target of over 30 frames per second (FPS) by exploiting FPGA and GPGPU acceleration transparently through the managed runtime system.

the amount of smart devices in our daily lives has dramatically increased. Many of these devices include sensors to capture their environment and communicate with other devices, forming the internet of things (IoT). A similar process of increasing intercommunication and digitization can be seen in industry where this development is called Industry 4.0. In this new era there is a strong demand for new computing architectures that fulfill the tight energy constraints as well as deliver enough on-chip processing performance. Off-the-shelf microcontrollers do not suffice both requirements as the power to performance ratio is too high. One solution are system on chip (SoC) architectures with domain specific application specific processors (ASIP). However, this new and competitive market requires a strongly reduced time to market. thus, it is necessary to speed up the design process and deliver enough flexibility to adapt to new applications. therefore, we propose a new SoC generation framework, which is based on an ASIP architecture. Architectural templates can be combined with existing intellectual property (IP) components, high-level synthesis (HLS) or hardware description language (HDL) code to speed up the design process. Both field programmable gate array (FPGA) and application specific integrated circuit (ASIC) back ends are supported. the architecture targets primarily multi-sensor and sensor fusion applications. A customizable MIPS processor with an adaptable compiler toolchain ensures interoperability in standard networks. the capabilities of our SoC architecture is demonstrated on two real world problems, including a performance demanding power quality monitoring application and a low-power swimming exercise tracking applications. Results show that the application constraints can be easily fulfilled while increasing speed and flexibility in the design process.

In the industry, reconfigurable real-timesystems are specified as a set of implementations and tasks with timing constraints. the reconfiguration allows to move from one implementation to another by adding/removing real-time tasks. Implementing those systems as threads generates a complex system code due to the large number of threads and the redundancy between the implementation sets. this paper shows an approach for software synthesis in reconfigurable uniprocessor realtimeembeddedsystems. Starting from the specification to a program source code, this approach aims at minimizing the number of threads and the redundancy between the implementation sets while preserving the system feasibility. the proposed approach adopts Mixed Integer Linear Programming (MILP) techniques in the exploration phase in order to provide feasible and optimal task model. An optimal reconfigurable POSIX-based code of the system is manually generated as an output of this technique. An application to a case study and performance evaluation show the effectiveness of the proposed approach.
