multiplexed bus

views updated

multiplexed bus A type of bus structure in which the number of signal lines comprising the bus is less than the number of bits of data, address, or control information being transferred between elements of the system. For example, a multiplexed address bus might use 8 signal lines to transmit 16 bits of address information. The information is transferred sequentially, i.e. time-domain multiplexed, with additional control lines being used for sequencing the transfer.
