Abstract: 1316348 Error handling INTERNATIONAL BUSINESS MACHINES CORP 20 Oct 1970 [25 Nov 1969] 49656/70 Heading G4A Data processing apparatus for processing data words containing k data bits and (n - k) check bits according to an (n, k) cyclic code includes (n - k) logic circuits arranged to feed result signals into respective stages of an (n - k) stage register and gating means arranged to feed the register contents and c > n - k data (or data and check) bits at a time into the logic circuits (with zero packing where necessary) according to a pattern defined by (c + n - k) rows out of the first (c+n+# - k) rows (the omitted rows being intermediate rows) of the autonomous matrix for the code so that, for the selected submatrix, gating occurs for each element a ij = 1 from the ith bit to the jth logic circuit where i # c and from the (i - c)th register stage to the jth logic circuit where c
