Abstract
A zero determination signal generating circuit which generates a zero determination signal for determining whether or not the output data of a shifter is zero is provided. With the zero determination signal generating circuit of the present invention, high-speed zero determination can be achieved. More specifically, in a case where the shifter functions as a left shifter, as a shifting operation of a left shifter unit (including a plurality of left shifters) is performed, predetermined bits in the outputs of left shifters having a shift amount of 0 are subjected to an OR operation or buffered so as to generate a zero determination signal. In a case where the shifter functions as a right shifter, as a shifting operation of a right shifter unit (including a plurality of right shifters) is performed, predetermined bits in the outputs of right shifters having a shift amount of 0 are subjected to an OR operation or buffered so as to generate a zero determination signal.
