(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)
