(AADL) A language allowing concise modular specifICation of multiprocessor architectures from the compiler/operating-system interface level down to chip level. AADL is rICh enough to specify target architectures while providing a concise model for clocked mICroarchitectures. ["AADL: A Net-Based SpecifICation Method for Computer Architecture Design", W. Damm et al in Languages for Parallel Architectures, J.W. deBakker ed, Wiley, 1989]. (2003-06-30)
