Addition algorithm, decimal adder with signed digit arithmetic p presented here was designed to establish the following facts: the redundant representation of a decimal digit xi by a 5-bit binary number Xi=3xi leads to a logical design of extreme simplicty; it is possible to form an additional algorithm for the adder so that it can be used to transform numbers written in a conventional decinal form into a signed digit form, and vice versa.
Addition algorithm, decimal adder, decimal addition algorithm, signed digit arithmetic, signed digit input transformamation algorithm, signed digit output transformation algorithm, signed digit transformation algorithm.
