Claims (1)

  1. n비트의 2진수 Ln을 m분의 1(단 m=2a-1, a는 2이상의 정의정수)에 제산하는 제산회로에 있어서 제산을 다음식으로 표시되는 급수로 전개해서 설정하는 수단을 가지고,
    단
    상기와 같이 전개되는 급수에 따라 상기 급수의 각항의 소수점 이하를 상위 비트로부터 a비트씩 분할하고 각항이 대응되는 a비트 분할부를 가산하는 제1의 가산수단과, 상기 제1의 가산수단의 가산결과에서 소수점 이하로부터의 정수자리로의 자리올림을 판정하는 판정수단과, 상기 급수의 각항의 정수자리 및 상기 판정수단으로부터 얻어지는 정수자리에서 자리올림치를 가산하는 제2의 가산수단을 구비하고, n비트의 2진수를 m분의 1로 제산하도록 구성된 것을 특징으로 하는 제산회로.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
