Abstract

In the usual two's complement representation of data, sign extensions in the higher-order bit positions can lead to a great deal of data bus switching activity. It is shown that the use of signed-digit representations can mitigate this effect. A negabinary representation (equivalent to a non-redundant sign-digit formulation) reduced data bus switching activity to a degree comparable to that provided by the better-known sign-magnitude notation.
