“…VIDAF focuses on the advancement of this research topic, through the demonstration of reliable methods and approaches that define the architectural framework for building reliable and cost-efficient real-time control systems and applications based on general-purpose hardware/software components, minimizing the use of custom-built solutions and products. Solutions have been proposed to support the development of similar architectural frameworks, particularly for embedded systems, but apart from a few [27][28][29], the majority is based on specialized mixed hardware and software components and approaches [30,31]. In the work of Ma et al [27] a low-cost, reusable, reconfigurable platform is proposed that enables integrated design and implementation of embedded control systems, but in simulation only (Scilab).…”

“…The work of Sarkar [28] proposes a modular approach for the design, implementation, and application of microcomputer-based embedded systems using open-source hardware and software platforms, but in small-scale applications. In the work of Bundalo et al [29], a theoretical only concept is presented of optimizing commercial off-the-shelf (COTS) selection process using a prototype framework approach.…”

The challenge of keeping the development and implementation of real-time control systems reliable and efficient and at the same time, low-cost and low-energy, is getting harder. This is because system designers and developers are faced with the dependability, inflexibility and often high-cost of specialized or custom-built hardware and software components. This research attempts to tackle issues such as the reliability and efficiency of real-time control systems and advance further the current state-of-the-art. For this purpose, a strong emphasis is placed on finding novel efficient solutions based on standardized and commercially available off-the-shelf hardware/software components. In this direction, this research applies credible and feasible methodologies (e.g., model-based design, component-based design, formal verification, real-time scheduling, prototyping, and validation) in an innovative enhanced way. As an important outcome, a versatile integrative design approach and architectural framework (VIDAF) is proposed, which supports the development and implementation of reliable real-time control systems and applications using commercial off-the-shelf (COTS) components. The feasibility and applicability of the proposed system’s architecture are evaluated and validated through a system application in embedded real-time control in manufacturing. The research outcomes are expected to have a positive impact on emerging areas such as the Industrial Internet of Things (IIoT).

Performance Assessment of Linux Kernels with PREEMPT_RT on ARM-Based Embedded Devices

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.
