Linear codes for single error correction in symmetric and asymmetric computational processes

A linear coding scheme for the correction of all possible single errors during arithmetic operations on binary number representations is discussed. The coded form of a number
k
is the binary representation of the number
kt
, where
t
is a positive integer. The code corrects all errors of the form
\pm2^i
, where
i
is less than
n
, the number of digits in the code words. The problem of determining the largest number
k
which may be encoded for a particular value of
t
is discussed. It is also shown that as the number of arithmetic operations to be performed increases, the use of this coding scheme becomes more significant in improving the reliability of the computational unit. An asymmetric process (in which only 1-errors or only O-errors are to be corrected) is also investigated and compared with the symmetric process.
