Multiplexing onto busses is a common technique, but there are times when the overhead for tag bits is unacceptable. In a multiprocessing implementation, interprocessor communication lines must be held to a minimum. This article describes a way to multiplex information on interface lines without using tags. A simple sequence is described for carrying the same information as tagging without the overhead in interface lines.
