ABSTRACT:
A semiconductor arithmetic circuit which realizes multiple-item addition processing at high speed and with a small surface areas The semiconductor arithmetic circuit adds a plurality of data expressed in binary format which is provided with terminals for the simultaneous input of the plurality of data, a mechanism for conducting a batch addition operation with respect to all the bits of the plurality of data, and for generating an analog or multi-valued signal having a linear relationship with the results of this addition and a mechanism for converting the analog or multi-valued signal to a digital signal. The plurality of data comprise bit data signals, and 4 or more of these are subjected to batch addition. A plurality of bit groups including a plurality of connected bits are also subjected to batch addition.
