Operating system architecture for supporting generations of microkernel

Abstract

The present invention relates to a computer operating system, and proposes a novel OS architecture to provide compatibility of different generations of user applications and operating systems. In addition, the OS also realizes a refined structure based on a module, and is used for customizing and completely accessing hardware functions. OS and its kernel can be developed for new functions and hardware without compromising and rewriting existing software components and applications. The architecture is represented as a COM component architecture in which the ACOM has an invariant interface andits normative evolution, allowing components to freely program code implementations. Wherein the possibility that the modular microkernel itself and the OS can run microkernel containers of all generations at the same time is included, and the possibility comprises / delegates or aggregates other needed components; a special marshalling mechanism reduces the header size by allowing executable filesto have address pointers for a single system interface instance for dynamic function import without having to recompile earlier executable files in the application according to the latest version of the OS system library.

Description

Technical field[0001]The present disclosure relates to computer engineering, and more particularly to the provision of an operating system (ОS) architecture that runs simultaneously on various generations of microkernels.Background technique[0002]Most modern operating systems are well-structured modular systems that can be developed, expanded, and transferred to new hardware platforms. One of the structural choices of the OS is to distinguish between single-chip architecture and micro-kernel architecture.[0003]The kernel is the central part of the operating system and provides applications with coordinated access to computer resources (such as processor time, memory, external hardware, and input and output peripherals). The kernel usually provides file system and network protocol services. A microkernel (μ kernel) is an operating system kernel with a minimal set of functions.[0004]Microkernels are conditionally divided into multiple generations. Different generations of microkernels...

Problems solved by technology

[0009] However, prior art OS architecture solutions have reduced functionality, in particular, none of them can provide simultaneous operation of various generations of microkernels
