On Negabinary-Binary Arithmetic Relationships and Their Hardware Reciprocity

This correspondence emphasizes the close relationship between binary addition and negative negabinary addition (n.n.b.a.). This is established by describing two possible ways of utilizing binary adders for performing n.n.b.a. Similar techniques of using n.n.b.a. adders for binary addition are also outlined and thus, negative addition is seen to be a primitive operation. These algorithms lead to four simple conversion processes of numbers from binary to negabinary system and vice versa.
