Super Pipelined Digit Serial Adders for Multimedia and e-Security

Adnan Gutub, Mohammad Ibrahim, and Muhammad Amer Araman

Abstract

This paper presents super-pipelined models of conventional adders that use digit serial addition. We pipeline three adders: ripple carry, carry select, and carry lookahead showing the pipelining effect in their speed and area. An improvement to the pipelined carry lookahead adder is proposed showing interesting results.
