Methods, systems and computer readable storage medium embodiments for communicating over a data bus include, determining a number of changes in bit value in respective bit positions between a previous bit string and a current bit string, transmitting either the current bit string in an inverted form over the data bus if the determined number of changes in bit value exceeds a threshold or the current bit string in non-inverted form if the determined number of changes in bit value does not exceed a threshold, and transmitting an additional at least one bit along with the current bit string having a logic value that indicates whether the current bit string is in an inverted form or non-inverted form. Methods, systems, and computer readable storage medium embodiments for receiving bit strings over a bus are also disclosed.
