PURPOSE:To perform the pre-processing of division of the high radixes at high speed in regard of the pre-processing of a division circuit. CONSTITUTION:A pre-processor of a division circuit of a high radix division system consists of a 1st zero counter 1 which counts (n) bits in a single units among those 0 bits which are continuous at the heads of an input divisor and an input dividend, a 1st shifter 2 which shifts the (unit number X n bits) obtained from the divisor end the dividend by the counter 1, a 2nd counter 3 which counts continuously the 0 bits at the shifted divisor, a latch 4 which stores the value of the counter 3, and a 2nd shifter 5 which shifts the divisor by the count value of the counter 3 and the dividend by the count value outputted from the latch 4 respectively. |
