In the business world, the use of Agile methodologies has been demonstrated as providing a pro-active, rather than reactive,
path for the developer to create defect-free products. Although similarities exist with business desktop and line-of-business
systems, the closer connection of signal processing systems to the hardware side of a product, and associated physical constraints,
makes the adaption of desktop Agile methodologies for the embedded world difficult; and the adoption of these methodologies
by developers problematic. We focus on our experiences in developing test frameworks to support transforming a subset of extreme
programming from the world of desktop applications into a suitable embedded domain production methodology. Details are provided
of the issues surrounding an Embedded xUnit testing framework that will permit development of digital signal processing applications on a wide range of standalone and
multi-processor systems in research, teaching and commercial development environments.
Michael Smith received his B.Sc. degree in Physics from the University of Hull, England and his Ph. D. degree from the University of Alberta, Canada. During that time he used high-speed helium-driven turbines as a mechanical technique for signal averaging prior to modeling solid state nuclear magnetic resonance signals. In 1971, he undertook research as Physics and Pathology post-doctoral fellow at the University of Calgary, Canada to design equipment and algorithms to differentiate normal and cancerous tissues in breast biopsy samples. In 1981, following a period of teaching Physics, Mathematics and Computer Science in high school, he became an Associate Professor at the Department of Electrical and Computer Engineering, University of Calgary, Canada. He became a Full Professor in Electrical Engineering in 1985 and an Adjunct Professor in Radiology in 2002. He consults with industry on issues related to embedded system development and reliability. His current research interests involve the development of reliable multi-processor biomedical embedded systems for real time analysis of cerebral blood flow in stroke patients; an increasing common disease with considerable personal and societal impact. He has published over 200 journal, conference and commercial papers on biomedical, computer and software engineering algorithms and processes (see for recent directions). James Miller received his B.Sc. and Ph.D. degrees in Computer Science from the University of Strathclyde, Scotland. During this period, he worked on the ESPRIT project GENEDIS on the production of a real-time stereovision system. Subsequently, he worked at the United Kingdom’s National Electronic Research Initiative on Pattern Recognition as a Principal Scientist, before returning to the University of Strathclyde to accept a lectureship, and subsequently a senior lectureship in Computer Science. Initially, during this period his research interests were in Computer Vision, and he was a co-investigator on the ESPRIT 2 project VIDIMUS. Since 1993, his research interests have been in Software and Systems Engineering. In 2000, he joined the Department of Electrical and Computer Engineering at the University of Alberta as a Full Professor and in 2003 became an Adjunct Professor at the Department of Electrical and Computer Engineering at the University of Calgary. He is the principal investigator in a number of research projects that investigate software verification, validation and evaluation issues across various domains, including embedded, web-based and ubiquitous environments. He has published over 100 refereed journal and conference papers on Software and Systems Engineering (see for details on recent directions); and currently serves on the program committee for the IEEE International Symposium on Empirical Software Engineering and Measurement; and sits on the editorial board of the Journal of Empirical Software Engineering. Steve Daeninck was born in Canada. He received his B.Sc. degree in Electrical and Computer Engineering in 2001 and his Masters of Engineering in 2005, both from the University of Calgary, Calgary, Canada. From 2005 to 2008 he worked for NovAtel Inc., Calgary, as a Firmware developer in their OEM and Research departments. Currently he is working for Blackline GPS, Calgary in the R&D department as a Firmware Engineer. 相似文献
