Error Correction Circuit for Odd and Even Symbol Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing error correction technologies struggle to efficiently correct errors in data transmission through channels, particularly in computer memory systems, where single bit errors are common, and in communication systems, where multi-error and burst errors occur frequently.
Innovation Solution
The proposed error correction circuit utilizes a syndrome generation circuit to generate odd and even syndromes based on an error correction code implemented as an H-matrix. This circuit includes a location information generation circuit to determine the location of errors in odd and even symbols, and a correction data generation circuit to correct errors in odd and even numbered symbols.

Engineering Contradiction Analysis
1Reliability
If conventional error correction codes (Hamming, BCH, RS) are used separately for different error types, then each code can correct its specific error type effectively, but the system requires multiple separate correction mechanisms increasing complexity
Solution Approach 1:
The patent combines multiple error correction capabilities into a single unified circuit that can handle both single-bit errors and multi-error/burst errors. The error correction circuit integrates the functionality of different correction codes (Hamming for single-bit errors, BCH/RS for multi-errors) into one system, eliminating the need for separate correction mechanisms and reducing overall system complexity while maintaining comprehensive error correction capability
Solution Approach 2:
The error correction circuit is designed with multi-functionality to handle various error types universally. It can detect and correct single-bit errors, multi-bit errors, and burst errors within a single circuit architecture, making the correction system adaptable to different error scenarios without requiring separate dedicated circuits for each error type
2Measurement precision
If separate correction circuits are used for odd and even symbols, then errors in specific symbol positions can be corrected more precisely, but the circuit complexity increases
Solution Approach 1:
The error correction circuit segments the error detection and correction process by position. It divides symbols into odd-positioned and even-positioned groups, applying position-specific correction strategies. This segmentation enables precise error location detection for specific symbol positions while maintaining an integrated circuit architecture that avoids the complexity of completely separate correction circuits for each position type
