“…There have also been a number of works relating to the use of component-based software engineering in real-time systems development. Whilst the majority of this research has been on providing a component model and a mapping from the model to an underlying OS, in recent years, there has been some research on using component models with the RTSJ [26][27][28]. For example, in [26], Etienne et al propose a component model which abstracts RTSJ memory management issues, simplifying the development process.…”

The OSGi Framework is a run-time environment for deploying service-containing Java components. Dynamically reconfigurable Java applications can be developed through the Framework's powerful capabilities such as installing, uninstalling, updating components at run-time, and allowing the substitution of service implementations at run-time. Coupled with the capability to be remotely managed, the OSGi Framework is proving a success in a variety of application domains. One domain where it is yet to make an impact is real-time systems. Despite the fact that OSGi components and services can be developed using the Real-Time Specification for Java (RTSJ), there are still a variety of problems preventing the use of the Framework to develop real-time systems. One such problem is a lack of temporal isolation. This paper focuses on how temporal isolation can be provided in the OSGi Framework as a first step towards using the Framework to developing real-time systems with the RTSJ.

The Real-time Specification of Java (RTSJ) has new memory management and scheduling models. These models require modification to existing software models and patterns or even the invention of new ones in order to be able to provide the patterns necessary to build reusable software components. In this paper we present a new memory model pattern associated with a set of integrated patterns and with it build simple and configurable software components.

“…One of the answers to these issues are component-oriented frameworks for RTSJ, such as [10,12,14], abstracting complexities of the RTSJ development from the developers. Nevertheless, the state-of-the-art solutions still need to fully address adaptability issues of real-time systems, separation of real-time and functional concerns, and suffer from the absence of a high-level process that would introduce real-time concerns during the design phase.…”

Abstract. The Real-Time Specification for Java (RTSJ) [13] is becoming a popular choice in the world of real-time and embedded programming. However, RTSJ introduces many non-intuitive rules and restrictions which prevent its wide adoption. Moreover, current state-of-the-art frameworks usually fail to alleviate the development process into higher layers of the software development life-cycle. In this paper we extend our philosophy that RTSJ concepts need to be considered at early stages of software development, postulated in our prior work [2], in a framework that provides continuum between the design and implementation process. A component model designed specially for RTSJ serves here as a cornerstone. As the first contribution of this work, we propose a development process where RTSJ concepts are manipulated independently of functional aspects. Second, we mitigate complexities of RTSJ-development by automatically generating execution infrastructure where real-time concerns are transparently managed. We thus allow developers to create systems for variously constrained real-time and embedded environments. Performed benchmarks show that the overhead of the framework is minimal in comparison to manually written object-oriented applications, while providing more extensive functionality. Finally, the framework is designed with the stress on dynamic adaptability of target systems, a property we envisage as a fundamental in an upcoming era of massively developed real-time systems.
