Abstract
A bus system includes a bus module which performs data transfer between a master module and a slave module and a detection module which detects transfer of transmission data from the master module to the bus module. When the bus module is shifted to a power saving mode and then is returned from the power saving mode, a power control module delays release of the power saving mode until a plurality of data transfer requests is detected. Accordingly, a power saving effect can be improved in the bus system.
