Abstract

A parity generator for multibit binary data in which only a subset of bits change at one time includes a circuit for determining whether the number of bits in the subset to be changed is odd or even. A toggle signal generator generates a toggle signal only if the number of bits to be changed is odd. A toggling circuit selectively changes the level of the parity bit in response to the toggle signal.
