Efficient Majority Logic Fault Detection with Difference-Set Codes for Memory Applications

In this Paper, we focus on a class of LDPC codes known as Euclidean Geometric (EG) LDPC codes, which are constructed deterministically using the points and lines of a Euclidean geometry. Minimum distances for EG codes are also reasonably good and can be derived analytically. memory error correction code has been implemented using pipelined cyclic corrector where majority logic gate determined the error .LDPC soft error decoding is also implemented for the same memory error detection and correction comparison of the results are done .as the majority gate can detect only upto 2 error the extending majority gate with ldpc soft decoding can decrease the bit error rate.
