Filed: 1966-10-07
Abstract: 1,102,320. Parallel binary adders. INTERNATIONAL BUSINESS MACHINES CORPORATION. 7 Oct., 1966 [12 Oct., 1965], No. 44807/66. Heading G4A. Transmission lines are provided for transmitting carry indicating signals from lower to higher stages of a multistage parallel binary adder. A 6-stage completion recognition parallel binary adder is shown in Fig. 3 wherein each stage in response to the respective input bit pairs (A 0 /B 0 , A 1 /B 1  &c.) generates either a carry signal C<SP>T</SP> (both input bits 1) or a no-carry signal C<SP>T</SP> (both input bits O) or no signal (input bits differ). The signals C<SP>T</SP> and C<SP>T</SP> are transmitted from lower to higher order stages on the lines 20, 21, respectively. The sum bits S 1 , S2 &c. are generated in each stage in response to the respective input bit pair and to the first signal received on either of the lines 20 or 21. The transmission of these signals and their detection in the stages is effected without the need for intermediate logic elements, thereby resulting in considerable increase in speed of operation. In order to overcome timing problems in the detecting circuitry when the stages are close together along the lines (i.e. to maintain adequate separation between pulses), adjacent stages are coupled together whereby those stages transmitting signals C<SP>T</SP> or C<SP>T</SP> suppress transmission of these signals from next preceding lower stages, the suppress signals being designated M. An alternate carry path between such adjacent stages is provided and is referenced C 1 , C 2  &c. In a modification (Fig. 4) whereby the transmission line may be further reduced in length the stages are coupled in pairs and the carry information transmitted along the lines 20, 21 relates to these pairs of stages rather than individual stages. Suppression of signal transmission and alternate carry paths are provided between adjacent pair groups as well as between stages of respective pairs. The directional couplers whereby the signals C<SP>T</SP> and C<SP>T</SP> are transmitted in the predetermined direction comprise lengths of transmission line placed adjacent and parallel to the lines 20 or 21, the lines 20, 21 and the directional couplers being terminated in their characteristic impedances. A binary adder made up of a plurality of sections, each section comprising an 8-stage adder as described above, is described in detail in the Specification, together with carry look ahead and other coupling arrangements between the individual sections of the adder.
