Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted between processing units using conventional fixed parameters, then the transmission process is simple, but transmission delays occur causing functional abnormalities
Solution Approach 1:
The patent applies dynamics by transitioning from fixed transmission parameters to dynamic parameter adjustment. The system continuously monitors transmission status and adapts physical parameters (voltage, frequency, timing) in real-time based on actual transmission conditions, allowing the transmission characteristics to change dynamically rather than remaining static.
Solution Approach 2:
The patent implements parameter changes by modifying physical transmission parameters such as voltage levels, clock frequency, and timing intervals based on transmission status. When delays are detected, the system adjusts these parameters to optimize transmission speed and reliability, directly addressing the contradiction between simple fixed-parameter operation and reliable adaptive transmission.
2Reliability
If transmission parameters are fixed, then the control process is simple, but transmission delays cause IP core hanging and SoC failure
Solution Approach 1:
The patent implements feedback mechanisms by monitoring transmission status and using this information to adjust transmission parameters. The system continuously observes transmission performance metrics and feeds this information back to the control logic, which then modifies parameters to maintain reliable operation, preventing IP core hanging and SoC failure.
Solution Approach 2:
The transmission system performs self-service by automatically detecting transmission issues and adjusting its own parameters without external intervention. The system monitors its own transmission status and autonomously modifies physical parameters to resolve delays, reducing the need for complex external control while improving reliability.
3Reliability
If dynamic parameter adjustment is implemented, then transmission reliability improves, but the system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-defining parameter adjustment strategies and thresholds before actual transmission occurs. The system prepares multiple parameter configurations and selection criteria in advance, allowing it to quickly switch to appropriate parameters when transmission issues are detected, reducing the complexity of real-time decision-making.

AI summary
Disclosed are a data transmission method and apparatus. The method comprises: first determining a transmission duration required for transmitting data to be transmitted between a first processing unit and a second processing unit; starting timing when it is detected that the data to be transmitted is transmitted from the first processing unit; and then, determining a physical parameter of the first processing unit when transmitting the data to be transmitted based on timing duration and a transmission status of the data to be transmitted; and transmitting the data to be transmitted to the second processing unit based on the physical parameter. According to this method, when there is a transmission delay in the data to be transmitted, the physical parameter of the first processing unit when transmitting the data to be transmitted can be adjusted, and the data to be transmitted can be transmitted to the second processing unit based on the adjusted physical parameter. Thus, the physical parameter during the data transmission process can be dynamically adjusted according to whether there is a delay in the data transmission, thereby reducing a possibility of data transmission delays and improving reliability of data transmission.
