Apparatus for data processing and method for processing data

A data processing apparatus and a data processing method are provided to reduce power consumption by reducing the minimum number of times of toggling of data. A data converting unit(200) converts the first data desired to be transmitted into the second data such that one of a plurality of bit signals constituting the second data has the same phase as those of one or more of different continuous bit signals. A transmitting unit(100) compresses and transmits the second data via a transport channel. A data restoring unit(300) restores the second data transmitted via the transmitting unit(100) into the first data. The second data converted by the data converting unit(200) includes one or more transmission groups whose minimum unit is two or more continuous bit signals having the same phase.
