Studying on AADL-Based Architecture Abstraction of Embedded Software

Since embedded software reaches a large scale and complexity, MDA and component-based development have become popular in embedded system development. Architecture-based software evaluation, maintenance and evolution can reduce cost of large-scale software, and raise the efficiency of maintenance and evolution. Especially, for legacy system, source code is regarded as the only dependable module to be reused in new systems. Thereby architecture abstraction from source code can describe the software at the level of architecture to support evaluation, maintenance and evolution. This paper studies on abstracting AADL model from C source code and introduces a set of mapping rules between the two languages. The mapping rules focus on identifying components and their relationships defined in AADL specification. An example is given at the end of the paper to demonstrate the algorithm.
