Abstract:
1. A method for reducing data transitions of a transmission end in a data transmission interface, the data transmission interface utilized for transmitting a plurality of data bits simultaneously, the method comprising: receiving first data and second data having a plurality of data bits, respectively, the first data being data transmitted by the transmission end of the data transmission interface and the second data being next data of the first data in a timing sequence; comparing corresponding data bits of the first data and the second data to compute a number of data bits undergoing data transition between the first data and the second data; checking if the number of data bits undergoing data transition between the first data and the second data is greater than half the number of the plurality of data bits to determine a voltage level of a control signal; activating an encoding mode to encode the plurality of data bits of the second data when the voltage level of the control signal conforms to a first voltage level; and outputting an encoding result corresponding to the second data to the transmission end.
