Abstract

본 발명에 의한 배럴 쉬프터회로에서는 N-(N/2) 배럴 쉬프터를 출력데이타의 상위 비트와 하위 비트를 분리하여 처리함으로써 최대 신호처리 지연시간을 감소시킬 뿐 아니라 하드웨어의 면적을 줄일 수 있는 이점이 있다.In the barrel shifter circuit according to the present invention, by processing the N- (N / 2) barrel shifter by separating the upper and lower bits of the output data, it is possible to reduce the maximum signal processing delay time and reduce the hardware area. have.
