Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate debugging platforms are used for kernel mode and user mode code, then each mode can be debugged with dedicated tools, but the overall debugging process becomes complex and inefficient
Solution Approach 1:
The patent merges kernel mode and user mode debugging into a single unified debugging platform. The debugging system integrates both debugging interfaces and enables simultaneous debugging of kernel and user mode code through coordinated core stopping and information collection mechanisms, eliminating the need for separate debugging platforms.
Solution Approach 2:
The unified debugging platform provides multi-functional capabilities to handle both kernel mode and user mode code debugging. The debugging interface can accommodate different code types by implementing universal stopping mechanisms and information collection functions that work across both modes through the multi-core processor architecture.
2Productivity
If multiple debugging platforms are maintained, then specialized debugging capabilities are preserved, but time and resources are wasted on switching between platforms
Solution Approach 1:
By combining kernel and user mode debugging into one platform, the system eliminates the time and effort required to switch between separate debugging environments. The unified platform maintains specialized capabilities for both modes while providing a single entry point for all debugging operations.
3Device complexity
If a unified debugging platform is implemented, then debugging complexity is reduced, but synchronization control between multiple cores becomes more difficult
Solution Approach 1:
The patent segments the multi-core processor into logical groups where each core can be independently controlled for debugging purposes. The stopping mechanism operates at the core level within these logical groups, allowing fine-grained synchronization control that simplifies the overall core coordination while maintaining unified platform operation.
