Abstract
A parity checking system for establishing integrity of data transfer on a wide bus. Each set of '4' bus lines of a multiple line bus is passed from a driver chip to a corresponding receiver chip. An added parity driver chip senses each corresponding bit line of each driver chip to develop a set of four parity signals for comparison with corresponding parity signals from each corresponding bit line of each one of a set of receiver chips. Any discrepancy will generate a parity error signal.
