Dynamic Line Encoding Lookup for Real-Time Channel Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for implementing encoding schemes in high-speed serial channels require offline reconfiguration of transceivers, making real-time changes impossible and inefficient, especially in multichannel devices where multiple channels must be taken offline for reconfiguration.
Innovation Solution
A programmable memory device, such as RAM, is used to dynamically configure encoding schemes like 8b10b, Interlaken, PCIE, and Ethernet, allowing for real-time switching between different encoding schemes based on transmission error rates, without interrupting data transmission, by acting as a lookup table and using a processor to implement the optimal encoding scheme.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed logic or hardware is used to configure a transceiver for a particular encoding scheme, then the encoding scheme is stable and reliable, but the entire channel must be taken offline for reconfiguration and cannot be changed in real time
Solution Approach 1:
The patent applies dynamics by replacing fixed logic with a reconfigurable logic device that can dynamically change encoding schemes in real-time. The system transitions from static hardware configuration to dynamic reconfiguration, allowing the transceiver to adapt encoding schemes without offline intervention while maintaining operational stability through controlled state transitions.
Solution Approach 2:
The patent implements parameter changes by modifying the logical configuration of the reconfigurable logic device to support different encoding schemes. By changing the configuration parameters of the logic device, the system can switch between various encoding schemes (such as 64b66b, 8b10b, 64b67b) without physical hardware changes, enabling both reliability and adaptability.
2Adaptability or versatility
If the entire channel is taken offline for reconfiguration, then the encoding scheme can be updated, but data transmission is interrupted and productivity decreases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple encoding schemes in the reconfigurable logic device before operation. This allows the system to switch between pre-prepared encoding configurations instantly without requiring offline reconfiguration, maintaining continuous data transmission while enabling encoding scheme updates.
Solution Approach 2:
The patent ensures continuity of useful action by implementing hot-swappable encoding scheme changes. The reconfigurable logic device can update encoding configurations while the channel remains active and data transmission continues uninterrupted, eliminating downtime and maintaining constant productive operation.
3Adaptability or versatility
If multiple channels are taken offline to reconfigure one channel in a multichannel device, then the encoding scheme can be changed, but the loss of time and productivity increases significantly
Solution Approach 1:
The patent applies segmentation by enabling independent reconfiguration of individual channels within a multichannel device. Each channel's reconfigurable logic device can be updated separately without affecting other channels, allowing one channel to be reconfigured while others continue operating, thus minimizing overall system downtime and time loss.
4Ease of manufacture
If fixed logic is used for encoding, then the hardware is simple and easy to manufacture, but real-time reconfiguration is impossible and device complexity increases when adaptability is added
Solution Approach 1:
The patent applies universality by using a reconfigurable logic device that can perform multiple encoding functions (64b66b, 8b10b, 64b67b, etc.) within a single hardware component. This multi-functional approach replaces what would otherwise require multiple separate fixed logic circuits, actually reducing overall device complexity while maintaining ease of manufacture through standardized reconfigurable components.
