Engineering Contradiction Analysis
1Extent of automation
If flash boot is performed using direct memory access (DMA), then the boot process can be automated, but the boot efficiency remains poor due to inadequate handling of transmission parameters
Solution Approach 1:
The patent implements a feedback mechanism where the detector circuit monitors the quality of boot information transmission and provides feedback to the control circuit. Based on this feedback, the control circuit dynamically adjusts transmission parameters (such as transmission rate or error correction level) to optimize boot efficiency while maintaining automation. This closed-loop control resolves the contradiction by enabling automated parameter optimization.
Solution Approach 2:
The patent introduces dynamic adjustment of transmission parameters during the boot process. Instead of using fixed transmission settings, the system adaptively modifies parameters based on real-time transmission conditions detected by the detector circuit. This dynamic approach improves boot efficiency while preserving the automated nature of the DMA-based flash boot process.
2Device complexity
If transmission parameters are not adjusted, then the boot process is simple, but the retransmission of boot information is unreliable
Solution Approach 1:
The patent implements a self-service mechanism where the system automatically detects transmission issues and adjusts its own parameters without external intervention. The detector circuit monitors transmission quality and triggers automatic parameter adjustment by the control circuit when reliability issues are detected. This self-adjusting capability improves retransmission reliability while maintaining the simplicity of the overall boot process from the user perspective.
Solution Approach 2:
A feedback loop is established between the detector circuit and control circuit, enabling the system to automatically respond to transmission quality variations. When the detector identifies poor transmission conditions, it triggers parameter adjustment through the control circuit, ensuring reliable retransmission without requiring complex manual configuration or external control.
3Reliability
If transmission parameters are dynamically adjusted, then retransmission reliability improves, but the system complexity increases
Solution Approach 1:
The patent divides the system into distinct functional modules: a detector circuit for monitoring transmission quality, a control circuit for parameter adjustment, and the DMA controller for execution. This segmentation allows each component to perform its specific function with simple logic, reducing overall system complexity while enabling reliable dynamic parameter adjustment. The modular architecture makes the complex function manageable and maintainable.
Solution Approach 2:
The patent integrates the detector and control circuits as part of the boot system architecture, allowing them to work together seamlessly during the boot process. By merging these functions into the existing DMA-based flash boot framework, the patent avoids adding significant external complexity while achieving improved retransmission reliability through coordinated parameter adjustment.
