    An Architecture Description Language for Embedded Hardware Platforms

    Embedded software development relies on various tools - compilers, simulators, execution time estimators - that encapsulate a more-or-less detailed knowledge of the target hardware platform. These tools can be costly to develop and maintain:significant benefits could be expected if they were automatically generated from models expressed in a dedicated modeling language.In contrast with Hardware Description Languages (HDLs), that focus on the internal structure and behavior of an electronic board of chip, Hardware Architecture Description Languages consider hardware as a platform for software execution. Such a platform will be described in terms of low-level programming interface (processor instruction set),resources (processing elements, memory and peripheral devices) and elementary services (arithmetic and logic operations, bus transactions).This paper gives an overview of HARMLESS (Hardware ARchitecture Modeling Language for Embedded Software Simulation), a new domain-specific language for modeling embedded hardware platforms. HARMLESS and its associated tools follow the Model-Driven Engineering philosophy: metamodeling and model transformations have been successfully applied to the automatic generation of processor simulators
