Abstract
This paper assesses the delay and area penalties incurred by adapting a parallel prefix adder to implement a variety of multimedia-motivated operations. Specifically, a 64-bit adder´s delay is found to increase by 36% and its area by 23% if sub-word operand, average, saturating arithmetic, comparison, and min-max operations are supported.
