Chapter 7: The Design of Multiplication and Division Circuits489Paper/Pencil Division StepAlign the divisor (Y) with the most significant end of the dividend•Let the portion of the dividend from its MSB to its bit aligned with the LSB of the divisor (X)Add/Subtract by comparing Xand Y:•If X≥Y, the quotient bit is 1 and perform the subtraction X -Y•If X< Y, the quotient bit is 0 and do not perform any subtractionsShift Yone bit to the right and repeat "add/subtract" stepUnsigned binary0111 = 7111110101 = 53111110101-111011001-111001011-1110100 = 4For unsigned numbers, straight paper/pencil method is fineNeed to find schemes that have minimum differences in implementation of signed (1's and 2's complementary) and unsigned numbers
