- In this paper, we add predictable and resource efficient event-triggered tasks in an RTOS. This is done by introducing an execution model suitable for example control software and component-based software. The execution model, denoted single-shot execution (SSX), can be realized with very simple and resource efficient run-time mechanisms and is highly predictable, hence suitable for use in resource constrained real-time systems. In an evaluation, we show that significant memory reductions can be obtained by using the SSX model.

Framework for Real-Time Analysis in Rubus-ICE

Konferensbidrag (refereegranskat)abstract
- In this paper we present the development of a plug-in framework for integration of real-time analysis methods in the Rubus Integrated Component Environment (Rubus-ICE). We also present the implementation, and evaluate the integration, of two state of the art analysis techniques (i) response-time analysis for tasks with offsets and (ii) shared stack analysis, as plug-ins, in the Rubus-ICE framework. The paper shows that the proposed framework is well suited for integration of complex analysis methods. However experience also show that analysis methods are not easily transferred from an academic environment to industry. The main reason for this, we believe, originates from differences in requirements and assumptions between industry and academia.

Supporting Engineering Requirements in the Rubus Component Model
- 2008
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In this paper we present a component model for development of distributed real-time systems.The model is developed to support development of embedded control systems for ground vehicles. The model aims at supporting three important activities in real-time development, (i) design, (ii) analysis and (iii) synthesis. These activities emphasise different and sometimes conflicting requirements that need to be balanced. For example, developers desire freedom in designing to solve complex tasks, analysis tools require the design to be formal enough for analysis and synthesis need to be efficient for low run-time footprint. We have considered industrial requirements for these activities and developed the RubusCMv3 component model. The model has been developed in close cooperation with industrial partners and it is currently being evaluated on real systems.
