Special Issue Information

Dear Colleagues,

The objective of this Special Issue is to invite original and high-quality papers that describe research, technical aspects, or developments in real-time embedded systems architecture, software, and applications. The research on real-time embedded systems has gained great interest in the last years as a result of the ever-increasing utilization of such systems in the IoT (Internet of Things), industrial IoT, cloud, and edge computing applications. However, the challenge of keeping the development and implementation of real-time systems reliable and efficient, and at the same time low-cost and energy efficient, is becoming more difficult. Systems designers and developers are faced with the dependability, inflexibility, and often high-cost of specialized or custom-built hardware and software components. In addition, the increase in the implementations of such systems and applications in surveillance and control (e.g., in smart home, energy systems, manufacturing, automotive and autonomous vehicles, and aerospace), and their special timing requirements, in particular for mission/life-critical systems, brings new challenges and issues in real-time embedded systems. Therefore, emphasis is placed on the investigation of the current advances and trends on new designs, developments, and applications.

This Special Issue welcomes contributions in the area of embedded and real-time systems and their emerging applications. Topics of interest include, but are not limited to, the following:

  • Real-time embedded systems and applications (e.g., in manufacturing, IoT, ubiquitous, cloud and edge computing, mechatronics and robotics, automotive and autonomous vehicles, health-care services, smart buildings, and smart cities)
  • Real-time system architectures and real-time operating systems
  • Real-time systems design and analysis tools and techniques
  • Energy efficient real-time systems and applications
  • Real-time embedded systems performance issues

An increasing number of battery-powered devices that are used outdoors or in mobile systems put emphasis on the power and energy efficiency as a form of trade-off between application performance and system power consumption. However, lack of objective metrics for the evaluation of application performance degradation poses difficulties for managing such trade-offs in real-time applications. The proposed methodology introduces metrics for modeling of application performance and the technique for its control, enabling more efficient power–performance trade-off management. The methodology allows for selective system performance degradation and fine-grained control of system behavior in the power–performance domain by extending the set of operating point parameters controllable through real-time application. The utilization and the effectiveness of the proposed methodology is evaluated in a simulated environment for different scenarios of the application execution, including system operation above the utilization bounds.

Embedded systems are widely used in various devices. PRES+ (Petri net- based Representation for Embedded Systems) has been used to model and analyze embedded systems. However, it cannot characterize the priority of events, and cannot fully express the complex data flow and control flow. To solve this problem, inhibitor arcs are added to PRES+ and PIRES+ (PRES+ with Inhibitor arcs) is obtained. However, PIRES+’s state space explosion problem is a handicap when modeling, verifying, and controlling complex, large embedded systems. To mitigate the state space explosion problem of PIRES+ and analyze complex embedded systems, we propose the place refinement approach and the place set refinement approach for PIRES+. Under specific conditions, several important properties of PIRES+, such as timing, functionality, reachability, liveness, and boundedness, are preserved by using these refinement approaches. In order to illustrate the effectiveness of these refinement methods, as an example, the modeling and analysis of a network communication system is proposed. The refinement methods proposed have certain feasibility and practicability and provide a more practical theoretical basis for the modeling of some embedded systems. Full article

This work investigates the real-time performance of Linux kernels and distributions with a PREEMPT_RT real-time patch on ARM-based embedded devices. Experimental measurements, which are mainly based on heuristic methods, provide novel insights into Linux real-time performance on ARM-based embedded devices (e.g., BeagleBoard and RaspberryPi). Evaluations of the Linux real-time performance are based on specific real-time software measurement modules, developed for this purpose, and the use of a standard benchmark tool, cyclictest. Software modules were designed upon the introduction of a new response task model, an innovative aspect of this work. Measurements include the latency of response tasks at user and kernel space, the response on the execution of periodic tasks, the maximum sustained frequency and general latency performance metrics. The results show that in such systems the PREEMPT_RT patch provides more improved real-time performance than the default Linux kernels. The latencies and particularly the worst-case latencies are reduced with real-time support, thus making such devices running Linux with PREEMPT_RT more appropriate for use in time-sensitive embedded control systems and applications. Furthermore, the proposed performance measurements approach and evaluation methodology could be applied and deployed on other Linux-based real-time platforms. Full article
