CHItecture, parallel> (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)
