Based on UML Embedded System Software Model ATM

To understand the development of embedded system software technology modeling problem,use UML construct embedded sys tem software model,a simple visual graphics describe system object,make theoretical modeling in the whole development process realized the standardization,the model can make the system and orderly,accurate to guide the follow-up control code compiling,greatly reducing the software development cycle,demonstrating,UML as a programming language has nothing to do with the general modeling language,can be applied to various types of embedded system software development,this paper will focus on how to design of embedded type system people use UML technology,and ATM system as an example to demonstrate the UML into specific people type system design process.
