Microkernel Generation Support via ACOM Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operating system architectures lack the ability to simultaneously operate microkernels of various generations, limiting their modularity and flexibility in hardware resource utilization and compatibility with different application software versions.
Innovation Solution
An operating system architecture based on the Adapted Component Object Model (ACOM) with a modular structure, allowing for the simultaneous operation of multiple microkernels through containment and aggregation mechanisms, enabling the reuse of components across different generations without compromising existing application functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a monolithic or traditional microkernel architecture is used, then the operating system can maintain a stable structure, but it cannot simultaneously operate microkernels of various generations or achieve high modularity
Solution Approach 1:
The kernel is divided into independent, interchangeable components (scheduler, file system, device drivers, etc.) that can be selectively loaded and unloaded. Each component is a separate module that communicates through standardized interfaces, allowing different generations of microkernel components to coexist and operate simultaneously within the same OS instance.
Solution Approach 2:
Multiple microkernel generations are nested within the same OS architecture through containment mechanisms. Older microkernel components can be contained within the new microkernel structure, allowing legacy applications to run alongside new features without requiring separate OS instances.
2Adaptability or versatility
If the operating system architecture is made more modular to allow component interchangeability, then adaptability improves, but system complexity increases
Solution Approach 1:
Standardized universal interfaces are defined for all kernel components, allowing any component to be interchangeable with others of the same type. The interface bus provides a universal communication mechanism that works across different component generations and types, reducing architecture complexity despite high modularity.
Solution Approach 2:
An interface bus acts as an intermediary layer between kernel components and the rest of the system. This mediator handles component registration, interface provisioning, and communication routing, simplifying the overall architecture by centralizing complexity in the interface management layer rather than in each component interaction.
3Adaptability or versatility
If new microkernel features are added to improve functionality, then adaptability increases, but compatibility with existing application software may be compromised
Solution Approach 1:
The microkernel architecture is dynamically configurable, allowing the system to adapt its component composition based on application requirements. New features can be loaded as optional components that coexist with legacy components, and the interface bus dynamically routes calls to appropriate component versions, maintaining backward compatibility while enabling new functionality.
Solution Approach 2:
The system allows parameter changes in microkernel components without breaking application compatibility. By using standardized interfaces and abstraction layers, internal parameter changes in new microkernel components do not affect the external behavior that applications depend on, ensuring forward compatibility.

AI summary
Computer operating systems are provided that allow for applications compatibility with different OS generations. Example operating systems are designed using an adapted COM (ACOM) component architecture with immutable interfaces and their specifications within same generation, allowing freedom of components programming code implementation. That includes: modular microkernel itself comprising an interface bus component, possibility for OS concurrently run microkernels of various generations, create new components by reusing (comprising/delegating or aggregating) other binary components; special marshalling mechanism reduces header size by allowing executable file to have a single system interface instance' address pointer for dynamic functions importing without need to recompile applications earlier executables in accordance with the latest versions of OS system libraries.
