  • Information processing apparatus, data transfer apparatus, and control method for data transfer apparatus
    Patent number: 9678562
    Abstract: A bus system comprises a plurality of bus modules each for performing data transfer between a master module and a slave module. A power control module controls transition to a power-saving mode of each bus module based on communication with the plurality of bus modules. The power control module comprises a plurality of control modules corresponding to the plurality of bus modules respectively. Each control module performs communication with the corresponding bus module using power control signals.
