Performance Optimization of HVD: An Error Detection and Correction Code
Fadnavis Shubham · 2013
Several EDAC techniques have been proposed and employed to effectively detect and correct errors introduced during data transmission over a communication channel or at the destination domain during storage. Some of these techniques can detect: only single error, all unidirectional errors, only burst errors, any bit in a data packet is change from one to zero or zero to one it means error is occur in same, errors with known locations assume a code is correct if the error location are known or cannot detect errors which appear in the same location in a pair of message codes. Coding techniques that detects and correct errors are more precise at detecting error locations and correcting them, however if more than one error occur, it becomes a challenge to detect all errors in a data frames and converted back its original form . In this paper, an advanced error detection and correction method to protect against errors is proposed. This method is based on 4D parities checking. This method, which is named HVD, provides very high detection coverage rate that can correct up to three flips in a data bit. The performance of HVD is optimize in comparison with the following coding techniques: CRC, Hamming codes. An independent design platform is utilized for the simulation by Xilinx 8.1 using ModelSim SE-EE 5.4a which shows a significant reduction in uncorrected errors during data transmission. The efficient performance of HVD makes it a more applicable coding technique for communication, data transmission, different protocols and other application.
