Abstract

A duplex data processing system includes two processors each provided with a bus connecting unit which disconnects the associated CPU bus from the cross connection bus in a separate mode or connects the CPU bus to the cross connection bus in a duplex mode. The system operates with a logically unified CPU bus through the connection of the internal CPU buses by the two bus connecting units in both processors.
