Abstract:
1. 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 so as to minimize a switching activity on the bus, the process comprising: associating to said digital signals an additional signal that is able to assume, at said given instants, different logic values according to whether the digital signal to which it is associated is transmitted in said non-encoded format and, at least in part, in said encoded format, respectively, so that said additional signal is able to modify its logic value between successive instants of said given instants; detecting for said digital signals a condition in which transmission on said bus in said non-encoded format and in said encoded format are able to give rise to an identical switching activity on the bus; and determining whether a digital signal to be transmitted on the bus at a given instant is to be transmitted in said non-encoded format or in said at least partially encoded format so as to cause the additional signal associated to said signal to be transmitted on the bus at a given instant to keep a logic value with respect to a logic value assumed by the additional signal for transmission on the bus for a preceding instant among said given instants.
