Low Power Error Correcting Codes Using Majority Logic Decoding
نویسنده
چکیده
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 decoding technique is used to detect errors in the memory. The method detects whether a word has errors in the first iterations, and when there are no errors the decoding ends without completing the rest of the iterations. This greatly reduces the average decoding time.

Error correction codes (ECCs) are commonly used to protect memories against errors. Among ECCs, Orthogonal Latin Squares (OLS) codes have gained renewed interest for memory protection due to their modularity and the simplicity of the decoding algorithm that enables low delay implementations. An important issue is that when ECCs is used, the encoder and decoder circuits can also suffer errors. I...

In a recent paper, a method was proposed to accelerate the majority logic decoding of difference set low density parity check codes. This is useful as majority logic decoding can be implemented serially with simple hardware but requires a large decoding time. In this brief, we study the application of a similar technique to a class of Euclidean geometry low density parity check (EGLDPC) codes t...

Reliability is a major concern in advanced electronic circuits. Errors caused for example by radiation become more common as technology scales. To ensure that those errors do not affect the circuit functionality a number of mitigation techniques can be used. Among them, Error Correction Codes (ECC) are commonly used to protect memories and registers in electronic circuits. When ECCs are used, i...
