DIVIDER AND IMAGE PROCESSING DEVICE USING DIVIDER

摘要

PROBLEM TO BE SOLVED: To provide a divider high in operation speed and reduced in, and an image processing device that high in operation speed and reduced in image level change by the use of the divider.;SOLUTION: With N, M and the selection of addition or subtraction all decided according to table data, a dividend is shifted by N bits by an N-bit shifter 1 and shifted by M bits by an M-bit shifter 2, and a value of the addition of the M-bit shift result to the N-bit shift result or a value of the subtraction of the M-bit shift result from the N-bit shift result of the dividend is selected according to the decision and outputted as a quotient.;COPYRIGHT: (C)2007,JPO&INPIT
