Method for accomplishing embedded system based on function component

The invention relates to a method for realizing an embedded system on the base of functional component. The method comprises separating system according to system functions, defining functional component standard interface and functional component package. The invention is characterized in that it employs software multiplying technology to perform modules separation according to the embedded operating system functions and make the functional modules be components which can be re-used; according to the embedded operating system with functional components, and different real needs, select components of different functions to construct services provided by the embedded operating system.
