Title: Carry signal propagating circuit
Inventor: YUGAWA AKIRA
IPC: G06F7/503
Filed: 1982-10-25
Abstract: PURPOSE:To attain the propagation of a carry signal at a high speed and to realize low power consumption by providing a carry signal propagating circuit on carry processing in addition processing in an arithmetic logical circuit and a multiplier of a computer. CONSTITUTION:In case when an addition result signal Pi of a half adder 301 is logic ''1'', namely, when a carry input signal inversion Ci-1 from the pre-stage is logic ''0'', a carry output signal invesion Ci propagates logic ''0''. In the half- adder 301, since it does not occur that both the addition result signal Pi and a carry signal Gi take logic ''1'', the carry signal Gi is logic ''0''. In this case, transistors TR302, 306 are opened, and TRs 305, 310 and 320 conduct, therefore, the carry input signal inversion Ci-1 is propagated and outputted as the carry output signal inversion Ci as it is. In this way, the carry input signal inversion Ci-1 from the pre-stage is transferred by two of transfer gates 310, 320 connected in parallel.
