Rxc Based Parity Sharing For Error Correction

Single error correction (SEC) code are used to detect and correct single bit errors by using hamming code method.SEC code requires more parity check bits. Product code can be detect and correct the single bit error. Product has the memory overhead problem. In parity sharing reduces the memory overhead and memory access complexity. Parity sharing reduces the parity check bits. Error correction codes are commonly used to protect memories from soft errors, which change the logical value of memory cells without damaging the circuit. Error Correction Codes (ECC) are commonly used to protect memories and registers in electronic circuits. When ECCs are used, it is of interest that in addition to correcting a given number of errors, the code can also detect errors exceeding that number. Error correcting codes led to the Hamming Codes, perfect 1-error correcting codes, and the extended Hamming Codes, 1-error correcting and 2-error detecting codes. The proposed system design using HDL the simulated using model sim and sythesis using xilinx synthesis technology. This approach reduces the memory overhead at the expense of a more complex access procedure. In this letter, an alternative scheme based on the use of parity sharing is proposed and evaluated. The results show that the new approach reduces significantly the memory overhead and is also capable of correcting single bit errors.
