ABSTRACT:
At least two Exclusive-OR (EOR) circuits for carry-out which output carry-out bits and the complementary signals thereof are provided in the 5-3 compressor circuits constituted by an Exclusive-OR (EOR) circuit group, and dual lanes are employed at least for carry-out. As a result, the number of inverters required can be reduced, increases in delay time can be suppressed, and fast addition operation can be achieved.
