Philips is one of the largest producers of consumer electronics in the world, with a strong position in (for example) the television market. Over the last years, televisions have grown to become software intensive systems - the software for a typical high-end television is over a million lines of code now. While the complexity of a single product is one problem to be mastered, managing the diversity and evolution of a family of products has become a major problem in itself. Moreover, televisions become increasingly integrated with other products, such as set-top boxes and storage devices (VCR, DVD), and in the resulting product population the problems mentioned above are even amplified.
As a solution to this, we designed Koala, a software component model with an accompanying architectural description language which have been optimized to handle complexity, diversity and evolution in resource constrained domains. In my talk I will present Koala, explaining the reasons behind its features, and showing typical examples of its use. I will also discuss some of our future plans. Koala has been used in industrial practice for almost 4 years now, and is currently being used by well over 100 software engineers in Philips.
About the Speaker
Rob van Ommering obtained his MSc in Physics at the Technical University of Eindhoven, The Netherlands in 1982. He joined Philips Research in Eindhoven in the same year, where he is now a principal research scientist . His research has included robotics, computer vision, artificial intelligence, machine learning, formal specification techniques, and formalization, visualization and verification of software architectures. His current interests are in all aspects of software architecture, with an emphasis on component technology and component based architectures, especially for product families and populations of resource constrained consumer products. As such, he is actively involved in the definition of software architectures for Philips' range of analogue and digital video products. He was the lead software architect for Philips' current TV software architecture. His e-mail address is Rob.van.Ommering@philips.com.
