ABSTRACT:
N (M+1) combining circuits mathematically arranged into M addition rows and a final carry resolution row so as to form N+M-1 columns, each column having an output, an N-bit multiplicand and an M-bit multiplier being connected to the combining circuits to provide digital, repeated addition type multiplication of the numbers represented by the N and M bits. The combining circuits in the final carry resolution row each have a carry bit input connected to the carry bit output of the previous combining circuit and an inverting amplifier is included in the carry propagation line every three or four combining circuits, to regenerate the carry bit. Further the entire multiplying circuit is formed on a single semiconductor chip and includes N inputs pads and N output pads with input latches and output latches for operating on both the N input bits and the M input bits with very little loss in time.
