Software Product Family Architectures - Engineering Run-Time Variability Dependencies in an FPGA-based Signal Processing Board
نویسنده
چکیده
In a software product family context, software architects anticipate product diversification and design architectures that support variants in both space (multiple contexts) and time (changing contexts). Product diversification is based on the concept of variability: a single architecture and a set of components support a family of products. Software product families need to support increasing amounts of variability, leading to a situation where variability dependencies become of primary concern. This paper discusses (1) a formalization of variability dependencies in the context of product family engineering and (2) a case study in developing a Real-Time Adaptive Signal Processing (RASP) system. RASP is a run-time reconfigurable signal processing board based on Field Programmable Gate Array (FPGA) technology. The formalization of variability dependencies has been used to design, implement and document RASP.
