Abstract

PURPOSE:To reduce the increase of the memory capacity despite the increase of the values of a divisor and a dividend by using a memory means which stores the quotients classified by the dividends and a processing means which selects the memory means and obtains the quotients of divisions. CONSTITUTION:A processing means 23 obtains the value of an input divisor and selects a 1st table 21 when the value of the divisor is kept within a 0-255 range. Then the relevant quotient is obtained from a divisor and a dividend. When the divisor is set within a 256-4095 range, the low-order 4 bits of the divisor are omitted. Then the relevant quotient is obtained from the high-order 8 bits and the dividend. The divisors are set within a 256-4095 range in a 2nd table 22 and therefore the 255 types of divisors can be obtained as the results of divisions owing to the omission of 4 bits. Thus it is possible to produce a table having the same capacity as the table 21 or those divisors in the 256-4095 range.
