Patent ID: 7076739

Claim:
A data computation apparatus comprising: an input unit including a plurality of input ports for data input; an output unit including a plurality of output ports for data output; an internal computing portion including a plurality of input terminals connectable to the input ports of the input unit and a plurality of output terminals connectable to the output ports of the output unit, the internal computing portion for performing computation based on data received by the input unit and to output computation results from the output unit; a list display unit for displaying on a screen a plurality of adjacent lists of connectors arranged in order of a list of the input ports of the input unit, a list of the input terminals of the internal computing portion, a list of the output terminals of the internal computing portion and a list of the output ports of the output unit, each of the lists being separately grouped as a connector; an input operation unit for designating the connectors on adjacent lists by a drag-and-drop operation to issue a connection instruction; and a connection controller for logically connecting the connectors on adjacent lists in response to the connection instruction by the input operation unit.
