A Suggestion for a High-Speed Parallel Binary Divider

A family of four procedures to compute the inverse 1/X of a given binary number X normalized between 0.5 and 1 is described. The quotient is obtained in redundant binary form, i.e., in a base 2 code in which digits can assume any positive or negative integer value. All methods here described can be implemented by combinatorial networks; the dividers realized in this way are very fast because all carry propagations take place at the same time.
