  • Method and apparatus for monitoring the consistency of successive binary code signal groups in data processing equipment
    Patent number: 4884273
    Abstract: For monitoring the consistency of successive binary code signal groups (CG) in data processing systems by parity bit comparison of the parity bit (PAKT) currently calculated for an effective code signal group (CG) to the parity bit (PAKT') predictively calculated at the appearance of the predecessor code signal group, and intermediately stored until the appearance of the effective code signal group (CG), the respectively predictive parity bit is calculated from the effective code signal group (CG) with an indicator signal (PW) indicating change of parity bit is generated upon transition to the successor code signal group and, subsequently, the predictive parity bit (PV) belonging to the successor code signal group is formed in conjunction with the current parity bit (PAKT) calculated for the effective code.
