Abstract

The invention belongs to an embedded operation system field which is characterized in that the system module is expanded into a file section containing metadata-metadata section, and an inside kernel component of the service interface function is contained in the metadata. Setting inside a storage address space: a read-only core domain and user domain capable of reading a core domain or co-machine co-domain or trans-domain operation, a network core domain and network user domain for trans-machine operation, building up a plurality of communication channels respectively for the operation of the inside kernel component adaptable for the co-domain to co-machine, trans-domain or trans-machine situations, setting shadow internal kernel component service interface function in the operation system kernel and storage address space for correspondent inside kernel components so as to solve the problems of download, visit and uninstall problems in the co-machine trans-domain or trans-machine inside kernel components. The invention also utilizes the platforms like the metadata management and buffer memory, component management, binding management, component buffer memory management platform to finish the dynamic assembling of the internal kernel component at the time of ensuring a favorable property and safety.

Description

technical field

[0001] The invention belongs to the field of embedded operating systems. technical background

[0002] With the development of computing technology, we have entered the network era from the PC era, and then entered the "pervasive computing era". "Ubiquitous computing" means, "no matter when and where, as long as there is demand, you can access the required information in some way". In the embedded system environment for pervasive computing, a large number of intelligent embedded systems need to exist, which can provide appropriate functions and services according to the change of the environment at any time.

[0003] At present, the embedded system hardware is developing rapidly, but the system software facing the changing environment at any time, especially the operating system's dynamic changes in the environment, limited hardware resources, hardware diversification, etc. adapt.

[0004] At present, the research on the operating system is roughly in thre...
