Patent ID: 7372916

Claim:
A process for transmitting at given instants digital signals on a bus, said digital signals being transmitted on the bus selectively in a non-encoded format and in an encoded format, comprising comparing a signal to be transmitted on the bus at an instant of said given instants with a signal transmitted on the bus at a preceding instant among said given instants so as to minimize switching activity on the bus, wherein said operation of comparing is carried out bit by bit in orderly sequence so as to identify in the signal to be transmitted and in the context of said signal transmitted on the bus at the preceding instant among said given instants, a first set of bits that are not changed, a second set of bits that are changed, and a marker bit that separates the bits of the first set from the bits of the second set in the signal to be transmitted on the bus at the instant of said given instants; and a decision whether to transmit said signal to be transmitted on the bus in non-encoded format and in encoded format is based on a position of the marker bit.
