Abstract
PURPOSE: To enable high speed operation processing simply, by setting the 2n notation in K-digit taking (n) as positive integer to dividend register, and performing division with 2n-1 through the use of divider consisting of a plurality of adders.
CONSTITUTION: Taking (n) as a positive integer, 2n notation in K-digit shown in equation I is set to the dividend register REG. Next, the division is made with 2n-1 by using the divider DIV consisting of the adder A01 in 5-digit. That is, all the coefficients of 2n notation are added, and if the content carry in excess of the lower n-digit as the result of addition is not 0, it is repeated until the carry is 0, and the carry as the result of addition and the content of lower n-digit are added. Next, if the result equals to 2n-1, the carry is 1 and the residual is made to 0. If not equal, all 1 detection in which the carry is made to 0 and the result of addition is taken as the residual, is made. Thus, the division by 2n-1 can be made in high speed through simple addition.
