Multiple Cell Errors Detection and Correction for OLS codes
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 3
Abstract
Error correction codes (ECCs) are commonly used to protect memories against errors. The proposed method we are we are detect the one or more errors and to correct single bit error. 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 are used, the encoder and decoder circuits can also suffer errors. In this brief, a concurrent error detection technique for OLS codes encoders and syndrome computation is proposed and evaluated. The proposed method uses the properties of OLS codes to efficiently implement a parity prediction scheme that detects all errors that affect a single circuit node.
