An Evolutionary Approach to Software Components in Embedded Real-Time Systems

Abstract
Component-based software engineering denotes the practice of building software from pre-existing smaller products, in particular when this is done using
standardized software component models. The main expected benefits of this
practice over traditional software engineering approaches are increased productivity
and timeliness of development projects. While the use of software
component models has become common for desktop and server-side software,
this is not the case in the domain of embedded real-time systems, presumably
due to the special requirements such systems have to meet with respect to
predictable timing and limited use of resources. Much research exists that
aims to define new component models for this domain, typically focusing on
source code components, static system configuration, and relatively narrow
application domains.
This dissertation explores the alternative approach of using components based
on binary code, allowing dynamic configuration, and targeting a broader domain.
A study of a general purpose component model shows that the model is
compatible with real-time requirements, although putting some restrictions on
its use may be necessary to ensure predictability. A case study demonstrates
how the model has been beneficially used in an industrial control system. The
dissertation furthermore proposes an approach for extending the component
model with run-time services for embedded real-time systems. It presents a
prototype tool for supporting such services, along with two empirical studies
to evaluate the approach and the tool as well as the component model itself.
One study shows that both the component model and the services provided
by the tool result in very modest and predictable run-time overheads. The
other study, evaluating the effects on productivity and quality of using the
approach in a software development project, did not produce quantitative
evidence, but concludes that the approach is promising and identifies possible
adjustments to it and opportunities for further studies.
