Abstract
A semiconductor integrated circuit according to one embodiment includes a plurality of flip-flop groups configured by dividing a plurality of flip-flops, connected in series, for carrying out a serial operation of serially transferring data, a continuous signal determination circuit configured to output a first signal if outputs of the flip-flops contained in the flip-flop group match, and output a second signal in other cases; and a clock gating circuit configured not to provide a clock signal when receiving the first signal and to provide a clock signal when receiving the second signal with respect to the flip-flops other than a head of the flip-flop group.
