Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmission methods require interface circuit switching between link training and service data transmission, leading to delays and losses that affect transmission quality and increase hardware costs due to the need for separate interface circuits for training and service data processes.
Innovation Solution
A data transmission method where the service data and training data share the same data structure, allowing for link training to be performed without switching interface circuits, thereby eliminating processing failures and reducing hardware requirements by using a single set of interface circuits for both processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If separate interface circuits are used for link training and service data transmission, then the data transmission rate can be optimized for each process, but the device complexity increases and switching delays occur
Solution Approach 1:
The patent applies universality by designing a single interface circuit that can handle both link training and service data transmission functions. The interface circuit is configured to adaptively switch between training mode and data transmission mode based on the current operation phase, eliminating the need for separate dedicated circuits for each function while maintaining optimized performance for both operations.
2Adaptability or versatility
If interface circuits are switched between link training and service data transmission, then the system can adapt to different transmission requirements, but transmission quality deteriorates due to switching delays and losses
Solution Approach 1:
The patent applies dynamics by implementing an adaptive interface circuit that can dynamically adjust its operating parameters and mode based on the current transmission phase. The interface circuit transitions smoothly between link training mode and service data transmission mode without requiring physical switching, thereby maintaining transmission quality while adapting to different transmission requirements through parameter adjustment rather than circuit switching.
3Manufacturing precision
If separate interface circuits are disposed for link training and service data transmission, then each process can use optimized parameters, but hardware costs increase
Solution Approach 1:
The patent reduces hardware costs by implementing a universal interface circuit that performs both link training and service data transmission functions. The single circuit is designed with configurable parameters that can be optimized for each specific operation mode, eliminating the need to purchase and integrate multiple separate interface circuits while maintaining the ability to apply optimized parameters for each transmission type.
4Adaptability or versatility
If interface circuit switching is performed between link training and data transmission, then the system can match circuits to specific tasks, but transmission efficiency decreases due to switching overhead
Solution Approach 1:
The patent maintains continuous data transmission by implementing an interface circuit that remains active throughout both link training and service data transmission phases. The circuit undergoes parameter reconfiguration rather than physical switching, allowing the useful action of data transmission to continue uninterrupted. This eliminates switching overhead and maintains high transmission efficiency while still adapting the circuit parameters to match the specific requirements of each transmission task.
