ABSTRACT:
The present invention provides employing differential transitional encoding with a differential bus. Employing the differential transitional encoding comprises dividing the differential bus into one or more groups comprising four bus lines. Employment of the differential bus also comprises asserting half the bus lines of a group during a bus data transfer, thereby defining an asserted set of bus lines and a de-asserted set of bus lines. The method and system further comprises transmitting data by differentially driving two of the bus lines, one bus line per set, by de-asserting one of the bus lines of the asserted set, and asserting one of the bus lines of the de-asserted set.
