<p>A data processing device, a mode management device, and a mode management method are provided to improve error tolerance of a computer with a dualized address crossbar by switching a first mode to a second mode of other crossbars affected by error, which occurs in one of a plurality of crossbars, while the crossbars are operated in the first mode dualizing the crossbars. A plurality of crossbars(40) are operated by a plurality of modes applied to connection among units. A mode switch switches the first mode to the second mode of mode setting of other crossbars affected by the error, which occurs in one of the crossbars, when the crossbars are operated in the first mode for dualizing the crossbars. The mode switch switches the mode of other crossbars by receiving an error notification signal from the error crossbar and transmitting a setting signal for switching the first mode to the second mode.</p> |
