EMBEDDED PLATFORM AND METHOD FOR DYNAMICALLY LINKING PROGRAM ON EMBEDDED PLATFORM

摘要

An embedded platform and a method for dynamically linking program on the embedded platform. The embedded platform comprises an intermediate layer, wherein the intermediate layer comprises interface classes; each interface class is obtained by encapsulating more than one function interfaces of an embedded operating system and corresponds to a virtual function table; and each element of the virtual function table corresponds to the more than one function interfaces one by one. The application programs to be linked comprise interface classes. The application programs are compiled into code segments with independent positions, and storage positions of the code segments compiled by different functions of the application programs are not intersected with each other; all the compiled code segments are directly copied into a memory of the embedded operating system; and interface class pointers are established and transmitted between the interface classes of the intermediate layer and the interface classes of the application programs, so as to realize dynamical linking of the programs.
