Architecture analysis and design language
Encyclopedia
The Architecture Analysis & Design Language (AADL) is an architecture description language
standardized by SAE.
AADL was first developed in the field of avionics
, and was known formerly as the Avionics Architecture Description Language. It is derived from MetaH, an architecture description language made by the Advanced Technology Center of Honeywell
. AADL is used to model the software
and hardware architecture of an embedded
, real-time
system. Due to its emphasis on the embedded domain, AADL contains constructs for modeling both software and hardware components (with the hardware components named "execution platform" components within the standard). This architecture model can then be used either as a design documentation, for analyses (such as schedulability and flow control) or for code generation (of the software portion), like UML

Embedded system
An embedded system is a computer system designed for specific control functions within a larger system. often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal...

Real-time computing
In computer science, real-time computing , or reactive computing, is the study of hardware and software systems that are subject to a "real-time constraint"— e.g. operational deadlines from event to system response. Real-time programs must guarantee response within strict time constraints...
