ABSTRACT:
A method and system for transmitting binary-coded data use partitioning of data words in a plurality of data nibbles. The data nibbles are coded using modified a 1-bit hot coding format that transforms a data nibble in a data segment including a plurality of bit groups. A change in a digital state at a bit position in a more significant bit group is maintained at that bit position in less significant bit groups, and information is transmitted in a form of a transition between digital states. The data segments are transmitted in phases each including one bit group from each data segment. At a receiving terminal, the bit groups are converted back in the binary-coded data words. In one application, the invention is used to reduce power consumption during data transmissions to and from an integrated circuit device.
