Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Selection of an Information Coding Algorithm to Improve the Efficiency of Protection Against Errors in Specialized Computers A.A. PAVLOV, A.N. TSARKOV, YU.A. ROMANENKO, O.F. PASHAYEV, A.YU. ROMANENKO, F.A. PAVLOV An algebraic code has been developed that allows for the correction of errors in direct and inverse values of the code set when performing arithmetic and logical operations of the processor. The rules for grouping error syndrome bits into bits that determine: – a block of information bits containing an error; – an erroneous bit in a 3-bit information block. The properties of the algebraic code that provide the ability to correct: – single errors in information bits; – multiple errors in check bits; A decoding algorithm has been developed that generates the values of the error syndrome bits: – determining the address of the information block containing the error and the number of the erroneous bit in a three-bit information block; – providing the correction of multiple errors in check bits. Keywords: algebraic code, additional code, information block, inversion operation, single error, multiple error. DOI: 10.25791/pribor.2.2025.1559 Pp. 44-51.
