A separation circuit separates a 32-bit dividend, for example 1695, into 4-bit segments starting from the lowest bit and outputs 9 separated dividends (X0 to X8). The position of each separated dividend counted from a separated dividend having the lowest bit is called i (i=0 to 8). A first output circuit concatenates a separated dividend and 0s the number of which is equal to integer multiple of 4 bits with the 0s at the end of the separated dividend. Each calculation circuit outputs an 8-bit quotient that is obtained by dividing by 3(=2 n -1 and n=2) a numerical value created by the first output circuit. Each calculation circuit outputs from a second output circuit a first bit sequence that is the upper 4 bits of the 8-bit quotient, and a second bit sequence in which i sets of lower 4 bits of the 8-bit quotient are arranged. A quotient addition circuit outputs, as a quotient of 1695 divided by 3, the sum of values in each of which the first bit sequence is set at upper bits and the second bit sequence is set at lower bits. |
