The requirements on increasing functionality, quality, and, customisation, while reducing cost has lead to the introduction of an architecture centred development process for electronic systems at Volvo Cars. This process enables better control of system integration and achieving non-functional requirements, such as reusability, understandability, etc. The(More)
This paper studies the problem of automatically selecting a suitable system architecture for implementing a real-time application. Given a library of hardware components, it is shown how an architecture can be synthesized with the goal of fulfilling the real-time constraints stated in the system's specification. In case the selected architecture contains(More)
This paper compares different scheduling policies applied to distributed systems intended for automotive real-time control applications. We describe the characteristics of systems using fixed priority (FP) and static cyclic (SC) scheduling of processors and bus communication, with combinations ranging from FP bus-FP processors to SC bus-SC processors. FP(More)
In the automotive industry, embedded systems and software play an increasingly important role in defining the characteristics of the vehicles. Both the vehicles and the embedded systems are designed as product lines, and two distinct architecture processes can be identified. The revolutionary process develops the architecture of a new product line, and(More)
Successful systems are developed from a good understanding of two things: the features and functions desired by the customers, and the features and behaviour of the available components. A firm developing a complex technical system is also a complex technical system in itself, so the same two things need to be understood about the organisation. Much(More)
The presence of iduronic acid in chondroitin/dermatan sulfate changes the properties of the polysaccharides because it generates a more flexible chain with increased binding potentials. Iduronic acid in chondroitin/dermatan sulfate influences multiple cellular properties, such as migration, proliferation, differentiation, angiogenesis and the regulation of(More)
The use of electronics in vehicles is increasing quickly and the systems are becoming increasingly complex. This makes the engineering of these advanced computer-based systems more and more difficult. In particular, finding a good architecture is a prerequisite for successful design. In this study we investigate key issues related to real-world decisions(More)
