Semiconductor circuit for arithmetic processing and arithmetic processing method

摘要

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, and this computing unit computes input digit 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.
