Serial One-step Majority Logic Decoder for Eg-ldpc Code
نویسندگان
چکیده
In the modern digital system design the reliability and security of memories are essential considerations. As technology scales, memory devices become larger and more powerful error correction codes are needed to protect memories from soft errors. Low Density Parity Check (LDPC) Codes are the class of linear block codes which provide near capacity performance on large collection of data transmission channels while simultaneously feasible for implementable decoders. One specific type of LDPC codes, namely EGLDPC are used due to their fault secure detection capability, higher reliability and lower area overhead. One of the existing methods for error detection in EG-LDPC is the one step Majority Logic Decoder (MLD) method used to detect the error in memory device itself.

Low Power Error Correcting Codes Using Majority Logic Decoding
A low-density parity-check (LDPC) code is a linear error correcting code, and is used for transmitting message over a noisy transmission channel. A new class of error correcting codes called EG-LDPC (Euclidean Geometry-LDPC) codes and its encoder and decoder architectures for nanomemory applications is designed. EG-LDPC codes also have fault secure detection capability. One step majority logic ...

In recent years, memory cells have become more susceptible to soft errors. This must be protected with effective error correction codes. Majority logic decodable codes are suitable for memory applications because of their capability to correct large number of errors. Conversely, they increase the average latency of the decoding process because it depends upon the code size that impacts memory p...
