Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data processing circuits often require multiple iterations through data decoder circuits to recover original data, but these iterations do not always yield the best results, leading to inefficiencies in data recovery.
Innovation Solution
Implementing a data processing system with a local iteration determination and limiting circuit that adjusts the number of local iterations based on the quality of decoded outputs, selecting the number of iterations that yields the smallest number of unsatisfied checks, to optimize data decoding.

Engineering Contradiction Analysis
1Manufacturing precision
If a fixed number of local iterations is applied in the data decoder circuit, then the decoding process is simple to implement, but the decoding accuracy and convergence are not optimized
Solution Approach 1:
The patent implements dynamic iteration control by allowing the number of local iterations to vary based on decoding quality metrics. The iteration counter and quality assessment mechanism enable the system to adaptively adjust iteration count rather than using a fixed predetermined number, thereby optimizing decoding accuracy while managing complexity through structured control logic.
Solution Approach 2:
The system changes the iteration parameter dynamically based on decoding quality assessment. By monitoring metrics such as error correction effectiveness and convergence patterns, the system adjusts the number of local iterations as a controllable parameter, transforming a static configuration into an adaptive process that improves decoding precision.
2Reliability
If multiple passes are made through the data detector circuit and data decoder circuit, then data recovery chances are increased, but processing time and computational resources increase
Solution Approach 1:
The patent implements feedback mechanisms where the quality of decoded outputs from each local iteration is assessed and fed back to determine whether additional iterations are warranted. This feedback loop allows the system to terminate processing early when quality thresholds are met, avoiding unnecessary time consumption while maintaining high data recovery reliability through continuous quality monitoring.
Solution Approach 2:
The system performs partial iterations when sufficient decoding quality is achieved early in the process, rather than always completing the full predetermined number of iterations. This approach applies just enough processing effort to achieve reliable data recovery, avoiding excessive computation and time expenditure while maintaining high recovery rates.
3Manufacturing precision
If the number of local iterations is increased, then decoding quality may improve, but processing efficiency decreases
Solution Approach 1:
The patent makes the iteration count dynamic rather than fixed, allowing the system to increase iterations only when quality metrics indicate improvement is still possible. This dynamic adjustment optimizes the balance between decoded output quality and processing efficiency by applying additional computational effort only when beneficial.
Solution Approach 2:
The system treats the number of local iterations as a variable parameter that changes based on real-time quality assessment. By monitoring decoding progress and adjusting the iteration parameter accordingly, the system achieves high decoded output quality without unnecessarily reducing processing efficiency through excessive iterations.
