Abstract: The object "functional-structural-physical" three-layer description by ADL (Architecture Description Language) be built followed the "describe-synthesize" design methodology to acquire the ASIP (Application Specific Instruction Set Processor) executable model to realize automation design.And the complexity of the ASIP system is divided into different view of the model.ADL of pure forms of behavior is allowed to describe the abstract complex system.In addition,the language itself is very easy to be captured for implementation by software,so the ADL specification will drive all the ASIP design process.
