Construction of Object-Oriented Reverse Analysis and Design Model for the rCore Operating System

Software document is a file that records the composition and workflow of software, and it is an important basis for software maintenance and development. At present, we have the source program of the rCore operating system, but there is no document about the program composition and workflow. In this paper, based on the source program, the module files of the system are analyzed, and the object-oriented composition model and the cooperation model between module functions of the rCore operating system are generated in reverse, which completes the reverse engineering work of the system and lays the foundation for the continuous development and maintenance of the system.
