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 uses a unified syndrome computation unit, key equation solver, and error location determination unit that can be configured to process data from 1, 2, 4, or more lanes through reconfiguration of the communication lane interface and data routing, eliminating the need for separate FEC modules for each lane while maintaining error correction reliability.
Solution Approach 2:
The reconfigurable FEC module is designed with universal functionality to perform error correction for data received from any number of communication lanes (1, 2, 4, or more). The syndrome computation unit, key equation solver, and error location determination unit are configured to universally process error correction tasks across different lane configurations through reconfiguration of the communication lane interface and internal data routing, making the hardware adaptable to various system requirements without requiring dedicated modules for each lane count.
2Adaptability or versatility
If reconfigurable FEC module is used, then adaptability to different data rates is improved, but device complexity increases
Solution Approach 1:
The FEC module implements dynamic reconfigurability through the communication lane interface and internal data routing that can be adjusted based on the number of active communication lanes (1, 2, 4, or more). The syndrome computation unit, key equation solver, and error location determination unit are configured to dynamically adapt their operation to handle different data rates and lane configurations, allowing the system to optimize performance for various bandwidth requirements while using a single hardware implementation.
3Productivity
If multiple FEC modules are deployed for high bandwidth, then data transfer capacity is improved, but manufacturing costs and space requirements increase
Solution Approach 1:
The patent merges the functionality of multiple FEC modules into a single reconfigurable FEC module that can handle data from multiple communication lanes simultaneously. By consolidating the syndrome computation unit, key equation solver, and error location determination unit into one module that can be configured for 1, 2, 4, or more lanes, the system achieves high data transfer capacity through parallel lane processing while reducing the total number of FEC modules required, thereby lowering manufacturing costs and reducing the space needed for module deployment.
