1. A system for determining a sequence of signals representative of events comprising: at least a first input connection and a second input connection for carrying the signals representative of events; and an arbiter coupled to the first input connection and to the second input connection to receive signals representative of events from each of the input connections, the arbiter determining a temporal order of occurrence of the representations of events when such events arrive at time intervals greater than a specified amount, and arbitrarily assigning a sequence to one or the other of the events when such events arrive at time intervals equal to or less than the specified amount, the arbiter reporting one of the temporal order or arbitrary sequence as a sequence of output signals.
