Abstract
The present invention provides an efficient method of transferring multi-word data across a fixed width parallel bus normally transmitting a single word at a time by allocating part of the bus word to the transmission of a fractional address dividing the given addressing space into subaddresses or 'fractional addresses'. A data transfer request provides the desired fractional address and the data transfer response returns the fractional address value and the portion of the multi-word data corresponding to that fractional address.
