Using aspect-oriented concepts in the requirements analysis of distributed real-time embedded systems

Abstract

Distributed Real-time Embedded (DRE) systems commonly have several requirements that are difficult to handle when a pure object-oriented method is used for their development. These requirements are called non-functional requirements and refer to orthogonal properties, conditions, and restrictions that are spread out over the system. In general, the specification of those requirements using pure object oriented methods leads to intermixed specification with the functional requirements. This work presents a proposal to use the concepts of aspect orientation in the specification of DRE requirements at the system analysis phase, offering a link from those requirements to system elements in the design phase. To support our proposal, it was performed an adaptation of a method called FRIDA (From RequIrements to Design using Aspects) to the DRE generating the RT-FRIDA (Real-Time FRIDA). © International Federation for Information Processing 2007.
