A Division Algorithm for Signed-Digit Arithmetic
September 1968 (vol. 17 no. 9)
pp. 887-889
Abstract?The application of a fast division algorithm, particu-larly suitable for floating-point arithmetic, to signed-digit number systems is described. This method, based on the method of A. Svo-boda, is performed in two steps: 1) the divisor is adjusted to be of the form (1+e) where e is a fractional quantity, while the dividend is adjusted accordingly, and 2) the generation of each quotient digit is determined by only one digit in the partial remainder together with the transfer digit (or carry/borrow) emanating from it. A working example of radix 16 is given.
