ABSTRACT A fault-tolerant digital data processing system comprises a first input/output controller which communicates with at least one peripheral device over a peripheral device bus having first and second input/output buses, each carrying data, address, control, and timing signals from the input/output controller to the peripheral device. A device interface is coupled to the first and second input/output buses and to an associated peripheral device for transferring information between the buses and the associated peripheral device. In normal operation, the device interface applies duplicate information signals synchronously and simultaneously to the input/output buses for transfer to the input/output controller. The device interface also receives, in the absence of fault, duplicative information signal synchronously and simultaneously from the first and second input/output buses.
