Automatic generation of error control codes for computerapplications

摘要

This paper proposes a methodology, implemented in a tool, tonautomatically generate the main classes of error control codes (ECC's)nwidely applied in computer memory systems to increase reliability andndata integrity. New code construction techniques extending the featuresnof previous single error correcting (SEC)-double error detectingn(DED)-single byte error detecting (SBD) codes have been integrated innthe tool. The proposed techniques construct systematic odd-weight-columnnSEC-DED-SBD codes with odd-bit-per-byte error correcting (OBC)ncapabilities to enhance reliability in high speed memory systemsnorganized as multiple-bit-per-chip or card
