Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate FEC modules are used for each communication lane, then error correction reliability is improved, but device complexity and hardware costs increase
Solution Approach 1:
The patent combines multiple FEC processing functions into a single reconfigurable FEC module that can handle data from multiple communication lanes. The module includes a syndrome computation unit, key equation solver, and Chien search unit that can be configured to process either combined or separate lane data, eliminating the need for multiple independent FEC modules while maintaining error correction reliability.
Solution Approach 2:
The reconfigurable FEC module is designed to perform multiple functions: it can process data from a single communication lane or combine and process data from multiple lanes simultaneously. The module's configuration can be changed based on operational requirements, allowing one hardware unit to replace multiple specialized FEC modules, thereby reducing device complexity while maintaining reliability.
2Device complexity
If a single FEC module processes combined data from multiple lanes, then hardware complexity is reduced, but error correction performance may deteriorate
Solution Approach 1:
The FEC module incorporates dynamic reconfiguration capability that allows it to switch between different operational modes based on the communication conditions. The module can be configured to process combined data from multiple lanes when error rates are low, or switch to processing lanes separately when error correction performance requires it, thus maintaining reliability while using a single hardware unit.
Solution Approach 2:
The patent changes the operational parameters of the FEC module by allowing configuration of the syndrome computation unit and data processing paths. By adjusting parameters such as whether to combine lane data before syndrome computation or process each lane independently, the module can optimize error correction performance for different communication scenarios while maintaining reduced hardware complexity.
3Manufacturing precision
If FEC modules are designed for specific communication modes, then processing precision is improved, but adaptability to different communication modes deteriorates
Solution Approach 1:
The reconfigurable FEC module is designed with universal processing capabilities that allow it to handle multiple communication modes including single-lane and multi-lane configurations. The module can be programmed to optimize processing precision for each specific mode while maintaining the ability to adapt to different communication scenarios, eliminating the need for multiple mode-specific FEC modules.
Solution Approach 2:
The FEC module incorporates dynamic reconfiguration features that allow it to adapt its internal processing architecture based on the communication mode being used. The module can reconfigure data paths, syndrome computation configurations, and processing parallelism to optimize precision for the current mode while maintaining adaptability to future mode changes.
