In this episode, Peter Feiler, primary author of the Architecture Analysis & Design Language (AADL) standard, discusses the latest changes to the standard, the second version of which was released in January 2009. First published in 2004 by SAE International, AADL is a modeling notation that employs both a textual and graphical representation to provide modeling concepts to describe the runtime architecture of application systems in terms of concurrent tasks, their interactions, and their mapping onto an execution platform. Development organizations use AADL to conduct lightweight, rigorous, yet comparatively inexpensive analyses of critical real-time factors such as performance, dependability, security, and data integrity.
