APPARATUS HAVING FIRST BUS AND SECOND BUS CONNECTABLE TO I/O DEVICE, INFORMATION PROCESSING APPARATUS AND METHOD OF CONTROLLING APPARATUS

摘要

An apparatus connected to a first and second buses, the apparatus having a first controller that transforms first form data into second form data, transforms second form data into first form data, and outputs the transformed data, a second controller that transforms first form data into second form data, transforms second form data into first form data, and outputs the transformed data, a first distributing unit connected to the first and second controllers, the first distributing unit distributing first form data to the first and second controllers, respectively, a first selector that selects one of the second form data, and outputs the selected data, a second distributing unit connected to the first and the second controllers, the second distributing unit distributing second form data to the first and second controllers, respectively, and a second selector that selects one of the first form data, and outputs the selected data
