Abstract
There is provided a semiconductor circuit for arithmetic processing and an arithmetic processing method that can increase the rate of processing data and reduces the area of a circuit by suppressing wasteful processing. There is provided a computing unit for computing input data within a computation time unit and outputs a computation result representing a result obtained by the computation, and if a carry is generated in the computation a computation circuit (adders 1-3) for outputting carry data representing this carry, and delay means (memory 4) for delaying the computation result from the computation circuit by one computation time unit, are provided.
