Abstract

PURPOSE: To provide a pipeline multiplication system by which the correct results can be obtained in any case.
CONSTITUTION: A primary level module Mi, an intermediate module Mm determined by the level number of the multiplier factor and the multiplicand and the terminal module Mt are longitudinally connected. In the respective module, there are provided the selection circuits Sel1, Seln, Selt. When the inputs are not generated in the respective timing signal input ends T1, Tn, Tt, the outputs b0, bn, bt of the AND circuits Po, Pn, Pt are transmitted through the delay element D to input terminal of all the adders FA1, FAn, FAt as outputs D0, Dn-1, Dt-1. When the input is generated in the timing signal input terminal T1, Tn, Tt, the outputs of AND gate A1, An, At, the switching is carried out so as to transmit the outputs of AND gates A1, An, At to the input terminal b of all the adders FA1, FAn, FAt through the delay element D in the same manner as the above.
