Multiple Cell Upsets Correction for OLS Codes

K.Michael Angelo, P.Soundarya Mala

An Error Correction code with Parity check matrix is implemented which is other type of the One Step Majority Logic Decodable (OS-MLD) called as Orthogonal Latin Squares (OLS) codes. It is a concurrent error detection technique for OLS codes encoders and syndrome computation because of the fact that when ECCs are used, the encoder and decoder circuits can also suffer errors.These OLS codes are used to correct the memories and caches. This can be achieved due to their modularity such that the error correction capabilities can be easily adapted to the error rate or to the mode of the operation.OLS codes typically require more parity bits than other codes to correct the same number of errors. However, due to their modularity and the simple low delay decoding implementation these are widely used in Error Correction. All the errors that affect a single circuit node are detected by the parity prediction scheme. The area and latency values are monitored.
