Error-control coding in computers

In this article, intended for readers with basic knowledge in coding, the codes used in actual systems are surveyed. Error control in high-speed memories is examined, including bit-error-correcting/detecting codes, byte-error-correcting/detecting codes, and codes to detect single-byte errors as well as correct single-bit errors and detect double-bit errors. Tape and disk memory codes for error control in mass memories are discussed. Processor error control and unidirectional error-control codes are covered, including the application of the latter to masking asymmetric line faults.<
