Implementing Adaptability in Embedded Software through Aspect Oriented Programming

Reusability is the key to reduction in software costs for embedded systems. Software is only reusable if it can be adapted to different operational environments. Conventional software technologies promote functional adaptability. In the embedded world, however, non-functional aspects are especially important. This paper introduces Aspect Oriented Programming (AOP) as a technique to achieve adaptability to non-functional requirements and it presents the XWeaver tool. This is an aspect weaver that is specifically aimed at embedded applications, especially those with high criticality requirements. The paper describes the structure of XWeaver and discusses experience from its usage. * corresponding author
