Dual-Syndrome ECC Block for Continuous Codeword Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing error correction technologies experience latency when processing continuous code words, which hampers data processing performance in data transmission systems.
Innovation Solution
An error correction code block with dual-syndrome generators and selectors processes even and odd numbered code words separately, generating syndrome values without latency, enabling efficient error correction through error locator polynomials and Chien search calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a single syndrome generator processes continuous code words sequentially, then the device complexity is low, but the data processing speed decreases due to latency between continuous code words
Solution Approach 1:
The single syndrome generator is divided into two separate syndrome generators (first and second syndrome generators), each processing different sets of code words (even-numbered and odd-numbered respectively). This segmentation allows parallel processing of continuous code words, eliminating latency while maintaining organized data flow through dedicated processing paths.
2Productivity
If dual syndrome generators process code words in parallel, then the data processing speed increases with no latency, but the device complexity increases
Solution Approach 1:
The outputs from the first and second syndrome generators are merged through a selector that combines their respective syndrome values into a unified output stream. This merging allows the system to maintain high parallel processing throughput while consolidating the complex dual-generator output into a single manageable data flow for subsequent error correction processing.
Solution Approach 2:
The first and second syndrome generators perform preliminary syndrome value calculations on even-numbered and odd-numbered code words respectively, preparing processed data in advance. This preliminary action allows the selector to simply route pre-processed syndrome values without performing complex real-time processing, thereby maintaining high throughput while managing device complexity.
3Reliability
If code words are processed sequentially through a single generator, then the device structure is simple, but the error correction performance deteriorates due to processing delays
Solution Approach 1:
By segmenting the code word stream into even-numbered and odd-numbered groups processed by separate syndrome generators, the system eliminates processing delays between continuous code words. Each generator operates independently on its designated group, ensuring timely error detection and correction without sequential bottlenecks, thereby improving reliability while minimizing time loss.

AI summary
An error correction code block including dual-syndrome generators, which may process a plurality of successive code word without latency, is configured to calculate syndrome values of a corresponding even numbered codeword among the plurality of code words by using one of the dual-syndrome generators, and is configured to calculate syndrome values of a corresponding odd numbered codeword among the plurality of code words by using the other of the dual-syndrome generators.
